rustdoc: Erase `#![doc(document_private_items)]`

I just found out about the existence of `#![doc(document_private_items)]`. Apparently it was added by PR rust-lang#50669 back in 2018 without any tests or docs as a replacement for some specific forms of the removed `#![doc(passes)]` / `#![doc(no_default_passes)]`.

However, rustc and rustdoc actually emit the deny-by-default lint `invalid_doc_attributes` for it (but if you allow it, the attribute does function)! To be more precise since PR rust-lang#82708 (1.52, May 2021) which introduced lint `invalid_doc_attributes`, rust{,do}c has emitted a future-incompat warning for this attribute. And since PR rust-lang#111505 (1.78, May 2024) that lint is deny by default. I presume nobody knew this attribute existed and thus it was never allowlisted.

Given the fact that since 2021 nobody has ever opened a ticket ([via](https://github.com/rust-lang/rust/issues?q=is%3Aissue+document_private_items)) complaining about the lint emission and the fact that GitHub code search doesn't yield any actual uses ([via](https://github.com/search?q=%2F%23%21%5C%5Bdoc%5C%28.*%3Fdocument_private_items%2F+language%3ARust&type=code&ref=advsearch)), I'm led to believe that nobody knows about and uses this attribute.

I don't find the existence of this attribute to be justified since in my view the flag `--document-private-items` is strictly superior: In most if not all cases, you don't want to "couple" your crate with this "mode" even if you gate it behind a cfg; instead, you most likely want to set this manually at invocation time, via a build config file like `.cargo/config.toml` or via a command runner like `just` I'd say.

Because of this I propose to wipe this attribute from existence. I don't believe it's worth cratering this (i.e., temporarily emitting a hard error for this attribute and running crater) given the fact that it's been undocumented since forever and led to a warning for years.

## Rustdoc

- [Remove `#![doc(document_private_items)]`](rust-lang/rust#146495)
- [Include attribute and derive macros in search filters for "macros"](rust-lang/rust#148176)
- [Include extern crates in search filters for `import`](rust-lang/rust#148301)
- [Validate usage of crate-level doc attributes](rust-lang/rust#149197).  This means if any of `html_favicon_url`, `html_logo_url`, `html_playground_url`, `issue_tracker_base_url`, or `html_no_source` either has a missing value, an unexpected value, or a value of the wrong type, rustdoc will emit the deny-by-default lint `rustdoc::invalid_doc_attributes`.

<a id="1.93.0-Compatibility-Notes"></a>

## Compatibility Notes

- [Introduce `pin_v2` into the builtin attributes namespace](rust-lang/rust#139751)
- [Update bundled musl to 1.2.5](rust-lang/rust#142682)
- [On Emscripten, the unwinding ABI used when compiling with `panic=unwind` was changed from the JS exception handling ABI to the wasm exception handling ABI.](rust-lang/rust#147224) If linking C/C++ object files with Rust objects, `-fwasm-exceptions` must be passed to the linker now. On nightly Rust, it is possible to get the old behavior with `-Zwasm-emscripten-eh=false -Zbuild-std`, but it will be removed in a future release.
- The `#[test]` attribute, used to define tests, was previously ignored in various places where it had no meaning (e.g on trait methods or types). Putting the `#[test]` attribute in these places is no longer ignored, and will now result in an error; this may also result in errors when generating rustdoc. [Error when `test` attribute is applied to structs](rust-lang/rust#147841)
- Cargo now sets the `CARGO_CFG_DEBUG_ASSERTIONS` environment variable in more situations. This will cause crates depending on `static-init` versions 1.0.1 to 1.0.3 to fail compilation with "failed to resolve: use of unresolved module or unlinked crate `parking_lot`". See [the linked issue](rust-lang/rust#150646 (comment)) for details.
- [User written types in the `offset_of!` macro are now checked to be well formed.](rust-lang/rust#150465)
- `cargo publish` no longer emits `.crate` files as a final artifact for user access when the `build.build-dir` config is unset
- [Upgrade the `deref_nullptr` lint from warn-by-default to deny-by-default](rust-lang/rust#148122)
- [Add future-incompatibility warning for `...` function parameters without a pattern outside of `extern` blocks](rust-lang/rust#143619)
- [Introduce future-compatibility warning for `repr(C)` enums whose discriminant values do not fit into a `c_int` or `c_uint`](rust-lang/rust#147017)
- [Introduce future-compatibility warning against ignoring `repr(C)` types as part of `repr(transparent)`](rust-lang/rust#147185)

Cargo
-----
- [Enable CARGO_CFG_DEBUG_ASSERTIONS in build scripts based on profile]
  (rust-lang/cargo#16160)
- [In `cargo tree`, support long forms for `--format` variables]
  (rust-lang/cargo#16204)
- [Add `--workspace` to `cargo clean`]
  (rust-lang/cargo#16263)

Rustdoc
-----
- [Remove `#![doc(document_private_items)]`](rust-lang/rust#146495)
- [Include attribute and derive macros in search filters for "macros"](rust-lang/rust#148176)
- [Include extern crates in search filters for `import`](rust-lang/rust#148301)
- [Validate usage of crate-level doc attributes](rust-lang/rust#149197).  This means if any of `html_favicon_url`, `html_logo_url`, `html_playground_url`, `issue_tracker_base_url`, or `html_no_source` either has a missing value, an unexpected value, or a value of the wrong type, rustdoc will emit the deny-by-default lint `rustdoc::invalid_doc_attributes`.

Compatibility Notes
-------------------
- [Introduce `pin_v2` into the builtin attributes namespace]
  (rust-lang/rust#139751)
- [Update bundled musl to 1.2.5]
  (rust-lang/rust#142682)
- [On Emscripten, the unwinding ABI used when compiling with
  `panic=unwind` was changed from the JS exception handling ABI to
  the wasm exception handling ABI.]
  (rust-lang/rust#147224) If linking C/C++
  object files with Rust objects, `-fwasm-exceptions` must be passed
  to the linker now. On nightly Rust, it is possible to get the
  old behavior with `-Zwasm-emscripten-eh=false -Zbuild-std`, but
  it will be removed in a future release.
- The `#[test]` attribute, used to define tests, was previously
  ignored in various places where it had no meaning (e.g on trait
  methods or types). Putting the `#[test]` attribute in these places
  is no longer ignored, and will now result in an error; this may
  also result in errors when generating rustdoc. [Error when `test`
  attribute is applied to structs]
  (rust-lang/rust#147841)
- Cargo now sets the `CARGO_CFG_DEBUG_ASSERTIONS` environment
  variable in more situations. This will cause crates depending on
  `static-init` versions 1.0.1 to 1.0.3 to fail compilation with
  "failed to resolve: use of unresolved module or unlinked crate
  `parking_lot`". See [the linked issue]
  (rust-lang/rust#150646 (comment))
  for details.
- [User written types in the `offset_of!` macro are now checked to
  be well formed.]
  (rust-lang/rust#150465)
- `cargo publish` no longer emits `.crate` files as a final artifact
  for user access when the `build.build-dir` config is unset
