Rollup merge of #140894 - Urgau:check-cfg-rustdoc, r=GuillaumeGomez

Make check-cfg diagnostics work in `#[doc(cfg(..))]`

This PR makes it so that the check-cfg `unexpected_cfgs` lint, is correctly emitted in `rustdoc`'s `#[doc(cfg(..))]`.

This is achieved by adding a custom trait to `cfg_matches` (the method that emits the lint) which permits `rustc` and `rustdoc` to each have their way to emitting lints (via buffered lints/AST for `rustc` and via `TyCtxt`/HIR for `rustdoc`).

The reason this is required is because buffered lints operates on the AST but `rustdoc` uses the HIR and by the time `rustdoc` calls `cfg_matches` we are way passed the point where buffered lints have been drain and emitted.

Website | Getting started | Learn | Documentation | Contributing

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
