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

# `check-cfg`
The tracking issue for this feature is: [#82450](https://github.com/rust-lang/rust/issues/82450).
------------------------
This feature enables checking of conditional configuration.
# Checking conditional configurations
`rustc` accepts the `--check-cfg` option, which specifies whether to check conditions and how to
check them. The `--check-cfg` option takes a value, called the _check cfg specification_.

## `--check-cfg`: enables checking conditional configurations
This flag will enable checking conditional configurations.
Refer to the [Checking conditional configurations](check-cfg.md) of this book

These correspond to `#[cfg(verbose)]` and `#[cfg(feature = "serde")]` respectively.
