bors b92758a9ae Auto merge of #125219 - Urgau:check-cfg-cargo-config, r=fmease 
Update `unexpected_cfgs` lint for Cargo new `check-cfg` config

This PR updates the diagnostics output of the `unexpected_cfgs` lint for Cargo new `check-cfg` config.

It's a simple and cost-less alternative to the build-script `cargo::rustc-check-cfg` instruction.

```toml
[lints.rust]
unexpected_cfgs = { level = "warn", check-cfg = ['cfg(foo, values("bar"))'] }
```

This PR also adds a Cargo specific section regarding check-cfg and Cargo inside rustc's book (motivation is described inside the file, but mainly check-cfg is a rustc feature not a Cargo one, Cargo only enabled the feature, it does not own it; T-cargo even considers the `check-cfg` lint config to be an implementation detail).

This PR also updates the links to refer to that sub-page when using Cargo from rustc.

As well as updating the lint doc to refer to the check-cfg docs.
