Stabilize checking of cfgs at compile-time: `--check-cfg` option

This PR stabilize the `--check-cfg` CLI option of `rustc` (and `rustdoc`) 🎉.

In particular this PR does two things:
  1. it makes the `--check-cfg` option stable
  2. and it moves the documentation to the stable books

FCP: https://github.com/rust-lang/rust/issues/82450#issuecomment-1965328542

Resolves #82450
