Reorder trait bound modifiers *after* `for<...>` binder in trait bounds

r? `@fmease` or reassign if you're busy

I wanted to crater this to see what the consequences are. Otherwise, we may be able to make this into a lint if the crater fallout is really bad.

The motivation for this is because we currently parse:
```rust
T: async for<'a> Fn(&'a ())
```

Instead of:
```rust
T: for<'a> async Fn(&'a ())
```

I believe the latter to be the correct ordering of bounds, since the `async` keyword modifies the *trait* so it should be attached to the trait path.

Move binder and polarity parsing into `parse_generic_ty_bound`

Let's pull out the parts of rust-lang#127054 which just:
1. Make the parsing code less confusing
2. Fix `?use<>` (to correctly be denied)
3. Improve `T: for<'a> 'a` diagnostics

This should have no user-facing effects on stable parsing.

Rollup merge of rust-lang#127054 - compiler-errors:bound-ordering, r=fmease

Reorder trait bound modifiers *after* `for<...>` binder in trait bounds

This PR suggests changing the grammar of trait bounds from:

```
[CONSTNESS] [ASYNCNESS] [?] [BINDER] [TRAIT_PATH]

const async ? for<'a> Sized
```

to

```
([BINDER] [CONSTNESS] [ASYNCNESS] | [?]) [TRAIT_PATH]
```

i.e., either

```
? Sized
```

or

```
for<'a> const async Sized
```

(but not both)

### Why?

I think it's strange that the binder applies "more tightly" than the `?` trait polarity. This becomes even weirder when considering that we (or at least, I) want to have `async` trait bounds expressed like:

```
where T: for<'a> async Fn(&'a ()) -> i32,
```

and not:

```
where T: async for<'a> Fn(&'a ()) -> i32,
```

### Fallout

No crates on crater use this syntax, presumably because it's literally useless. This will require modifying the reference grammar, though.

### Alternatives

If this is not desirable, then we can alternatively keep parsing `for<'a>` after the `?` but deprecate it with either an FCW (or an immediate hard error), and begin parsing `for<'a>` *before* the `?`.

Rustfmt `for<'a> async` correctly

In rust-lang#127054, we decided to move the trait bound modifier for `async for<'a> Fn()`  to `for<'a> async Fn()`. This wasn't adjusted in rustfmt, so this PR implements that. It also requires consolidating the bound formatting into the `Rewrite` impl for `PolyTraitRef`.

Fixes rust-lang#131649

<a id="1.82.0-Cargo"></a>

## Cargo

-   [feat: Add `info` cargo subcommand](rust-lang/cargo#14141)

<a id="1.82.0-Compatibility-Notes"></a>

## Compatibility Notes

-   We now [disallow setting some built-in cfgs via the command-line](rust-lang/rust#126158) with the newly added [`explicit_builtin_cfgs_in_flags`](https://doc.rust-lang.org/rustc/lints/listing/deny-by-default.html#explicit-builtin-cfgs-in-flags) lint in order to prevent incoherent state, eg. `windows` cfg active but target is Linux based. The appropriate [`rustc` flag](https://doc.rust-lang.org/rustc/command-line-arguments.html) should be used instead.
-   The standard library has a new implementation of `binary_search` which is significantly improves performance ([#&#8203;128254](rust-lang/rust#128254)). However when a sorted slice has multiple values which compare equal, the new implementation may select a different value among the equal ones than the old implementation.
-   [illumos/Solaris now sets `MSG_NOSIGNAL` when writing to sockets](rust-lang/rust#128259). This avoids killing the process with SIGPIPE when writing to a closed socket, which matches the existing behavior on other UNIX targets.
-   [Removes a problematic hack that always passed the --whole-archive linker flag for tests, which may cause linker errors for code accidentally relying on it.](rust-lang/rust#128400)
-   The WebAssembly target features `multivalue` and `reference-types` are now
    both enabled by default. These two features both have subtle changes implied
    for generated WebAssembly binaries. For the `multivalue` feature, WebAssembly
    target support has changed when upgrading to LLVM 19. Support for generating
    functions with multiple returns no longer works and
    `-Ctarget-feature=+multivalue` has a different meaning than it did in LLVM 18
    and prior. There is no longer any supported means to generate a module that has
    a function with multiple returns in WebAssembly from Rust source code. For the
    `reference-types` feature the encoding of immediates in the `call_indirect`, a
    commonly used instruction by the WebAssembly backend, has changed. Validators
    and parsers which don't understand the `reference-types` proposal will no
    longer accept modules produced by LLVM due to this change in encoding of
    immediates. Additionally these features being enabled are encoded in the
    `target_features` custom section and may affect downstream tooling such as
    `wasm-opt` consuming the module. Generating a WebAssembly module that disables
    default features requires `-Zbuild-std` support from Cargo and more information
    can be found at
    [rust-lang/rust#128511](rust-lang/rust#128511).

Cargo
-----
- [feat: Add `info` cargo subcommand]
  (rust-lang/cargo#14141)

Compatibility Notes
-------------------
 - We now [disallow setting some built-in cfgs via the
   command-line](rust-lang/rust#126158) with
   the newly added
   [`explicit_builtin_cfgs_in_flags`]
   (https://doc.rust-lang.org/rustc/lints/listing/deny-by-default.html#explicit-builtin-cfgs-in-flags)
   lint in order to prevent incoherent state, eg. `windows` cfg active
   but target is Linux based. The appropriate [`rustc` flag]
   (https://doc.rust-lang.org/rustc/command-line-arguments.html)
   should be used instead.

- The standard library has a new implementation of `binary_search`
  which is significantly improves performance
  ([#128254](rust-lang/rust#128254)). However
  when a sorted slice has multiple values which compare equal, the
  new implementation may select a different value among the equal
  ones than the old implementation.

- [illumos/Solaris now sets `MSG_NOSIGNAL` when writing to
  sockets](rust-lang/rust#128259). This avoids
  killing the process with SIGPIPE when writing to a closed socket,
  which matches the existing behavior on other UNIX targets.

- [Removes a problematic hack that always passed the --whole-archive
  linker flag for tests, which may cause linker errors for code
  accidentally relying on it.]
  (rust-lang/rust#128400)

- The WebAssembly target features `multivalue` and `reference-types`
  are now both enabled by default. These two features both have
  subtle changes implied for generated WebAssembly binaries. For
  the `multivalue` feature, WebAssembly target support has changed
  when upgrading to LLVM 19. Support for generating functions with
  multiple returns no longer works and `-Ctarget-feature=+multivalue`
  has a different meaning than it did in LLVM 18 and prior. There
  is no longer any supported means to generate a module that has
  a function with multiple returns in WebAssembly from Rust source
  code. For the `reference-types` feature the encoding of immediates
  in the `call_indirect`, a commonly used instruction by the
  WebAssembly backend, has changed. Validators and parsers which
  don't understand the `reference-types` proposal will no longer
  accept modules produced by LLVM due to this change in encoding
  of immediates. Additionally these features being enabled are
  encoded in the `target_features` custom section and may affect
  downstream tooling such as `wasm-opt` consuming the module.
  Generating a WebAssembly module that disables default features
  requires `-Zbuild-std` support from Cargo and more information
  can be found at
  [rust-lang/rust#128511](rust-lang/rust#128511).
- [Rust now raises unsafety errors for union patterns in parameter-position]
  (rust-lang/rust#130531)

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they
represent significant improvements to the performance or internals
of rustc and related tools.

- [Update to LLVM 19]
  (rust-lang/rust#127513)

Pkgsrc changes:
 * Adapt patches, apply to new vendored crates where needed.
 * Back-port rust pull request 130110, "make dist vendoring configurable"
 * Disable "dist vendoring", otherwise cargo would try to access
   the network during the build phase.
 * Dial down the verbosity of the build by dropping -v argument to x.py.

Cargo
-----
- [feat: Add `info` cargo subcommand]
  (rust-lang/cargo#14141)

Compatibility Notes
-------------------
 - We now [disallow setting some built-in cfgs via the
   command-line](rust-lang/rust#126158) with
   the newly added
   [`explicit_builtin_cfgs_in_flags`]
   (https://doc.rust-lang.org/rustc/lints/listing/deny-by-default.html#explicit-builtin-cfgs-in-flags)
   lint in order to prevent incoherent state, eg. `windows` cfg active
   but target is Linux based. The appropriate [`rustc` flag]
   (https://doc.rust-lang.org/rustc/command-line-arguments.html)
   should be used instead.

- The standard library has a new implementation of `binary_search`
  which is significantly improves performance
  ([#128254](rust-lang/rust#128254)). However
  when a sorted slice has multiple values which compare equal, the
  new implementation may select a different value among the equal
  ones than the old implementation.

- [illumos/Solaris now sets `MSG_NOSIGNAL` when writing to
  sockets](rust-lang/rust#128259). This avoids
  killing the process with SIGPIPE when writing to a closed socket,
  which matches the existing behavior on other UNIX targets.

- [Removes a problematic hack that always passed the --whole-archive
  linker flag for tests, which may cause linker errors for code
  accidentally relying on it.]
  (rust-lang/rust#128400)

- The WebAssembly target features `multivalue` and `reference-types`
  are now both enabled by default. These two features both have
  subtle changes implied for generated WebAssembly binaries. For
  the `multivalue` feature, WebAssembly target support has changed
  when upgrading to LLVM 19. Support for generating functions with
  multiple returns no longer works and `-Ctarget-feature=+multivalue`
  has a different meaning than it did in LLVM 18 and prior. There
  is no longer any supported means to generate a module that has
  a function with multiple returns in WebAssembly from Rust source
  code. For the `reference-types` feature the encoding of immediates
  in the `call_indirect`, a commonly used instruction by the
  WebAssembly backend, has changed. Validators and parsers which
  don't understand the `reference-types` proposal will no longer
  accept modules produced by LLVM due to this change in encoding
  of immediates. Additionally these features being enabled are
  encoded in the `target_features` custom section and may affect
  downstream tooling such as `wasm-opt` consuming the module.
  Generating a WebAssembly module that disables default features
  requires `-Zbuild-std` support from Cargo and more information
  can be found at
  [rust-lang/rust#128511](rust-lang/rust#128511).
- [Rust now raises unsafety errors for union patterns in parameter-position]
  (rust-lang/rust#130531)

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they
represent significant improvements to the performance or internals
of rustc and related tools.

- [Update to LLVM 19]
  (rust-lang/rust#127513)
