Stabilize WebAssembly `multivalue`, `reference-types`, and `tail-call` target features

For the `multivalue` and `reference-types` features this commit is
similar to rust-lang#117457 in that it's stabilizing target features specific to
WebAssembly targets. The previous PR left out these two features because
they weren't expected to change much about compiled code so it was
unclear what the rationale was. It has [since been discovered][blog]
that `reference-types` can be useful as it changes the binary format of
the `call_indirect` instruction. Additionally [on Zulip][zulip] there's
a use case of detecting these features at compile time and generating a
compile error to better warn users about features not supported on
engines.

This PR then additionally adds the `tail-call` feature which corresponds
to the [tail-call] proposal to WebAssembly. This feature advanced to
"phase 4" in the WebAssembly CG awhile back and has been supported in
LLVM for quite some time now. Engines are finishing up implementations
or have already shipped implementations, so while this is a bit of a
late addition to Rust itself it reflects the current status of
WebAssembly's state of the feature.

A test has been added here not only for these features but other
WebAssembly features as well to showcase that they're usable without
feature gates in stable Rust.

## Compatibility Notes

-   [Enable by default the `LSX` target feature for LoongArch Linux targets](rust-lang/rust#132140)
-   [The unstable `-Zprofile` flag (“gcov-style” coverage instrumentation) has been removed.](rust-lang/rust#131829) This does not affect the stable flags for coverage instrumentation (`-Cinstrument-coverage`) and profile-guided optimization (`-Cprofile-generate`, `-Cprofile-use`), which are unrelated and remain available.
-   Support for the target named `wasm32-wasi` has been removed as the target is now named `wasm32-wasip1`. This completes the [transition](rust-lang/compiler-team#607) [plan](rust-lang/compiler-team#695) for this target following [the introduction of `wasm32-wasip1`](rust-lang/rust#120468) in Rust 1.78. Compiler warnings on [use of `wasm32-wasi`](rust-lang/rust#126662) introduced in Rust 1.81 are now gone as well as the target is removed.
-   [The syntax `&pin (mut|const) T` is now parsed as a type which in theory could affect macro expansion results in some edge cases](rust-lang/rust#130635 (comment))
-   [Legacy syntax for calling `std::arch` functions is no longer permitted to declare items or bodies (such as closures, inline consts, or async blocks).](rust-lang/rust#130443 (comment))
-   [Declaring functions with a calling convention not supported on the current target now triggers a hard error](rust-lang/rust#129935)
-   [The next-generation trait solver is now enabled for coherence, fixing multiple soundness issues](rust-lang/rust#130654)

Compatibility Notes
-------------------
- [Enable by default the `LSX` target feature for LoongArch Linux targets]
  (rust-lang/rust#132140)
- [The unstable `-Zprofile` flag ("gcov-style" coverage instrumentation)
  has been removed.](rust-lang/rust#131829)
  This does not affect the stable flags for coverage instrumentation
  (`-Cinstrument-coverage`) and profile-guided optimization
  (`-Cprofile-generate`, `-Cprofile-use`), which are unrelated and
  remain available.
- Support for the target named `wasm32-wasi` has been removed as
  the target is now named `wasm32-wasip1`. This completes the [transition]
  (rust-lang/compiler-team#607)
  [plan](rust-lang/compiler-team#695) for
  this target following [the introduction of `wasm32-wasip1`]
  (rust-lang/rust#120468) in Rust 1.78.
  Compiler warnings on [use of `wasm32-wasi`]
  (rust-lang/rust#126662)
  introduced in Rust 1.81 are now gone as well as the target is
  removed.
- [The syntax `&pin (mut|const) T` is now parsed as a type which
  in theory could affect macro expansion results in some edge cases]
  (rust-lang/rust#130635 (comment))
- [Legacy syntax for calling `std::arch` functions is no longer
  permitted to declare items or bodies (such as closures, inline
  consts, or async blocks).]
  (rust-lang/rust#130443 (comment))
- The `wasm32-unknown-emscripten` target's binary release of the
  standard library is now [built with the latest emsdk 3.1.68]
  (rust-lang/rust#131533), which fixes an
  ABI-incompatibility with Emscripten >= 3.1.42. If you are locally
  using a version of emsdk with an incompatible ABI (e.g. before
  3.1.42 or a future one), you should build your code with `-Zbuild-std`
  to ensure that `std` uses the correct ABI.
- [Declaring functions with a calling convention not supported on
  the current target now triggers a hard error]
  (rust-lang/rust#129935)
- [The next-generation trait solver is now enabled for coherence,
  fixing multiple soundness issues]
  (rust-lang/rust#130654)
