Wire up unstable rustc --check-cfg to rustdoc

This pull-request wire up the new unstable `--check-cfg` option from `rustc` to `rustdoc` as [requested](https://github.com/rust-lang/rust/pull/93915#discussion_r807560445) in the [pull-request](https://github.com/rust-lang/rust/pull/93915) that introduce `--check-cfg`.

The motivation was describe in the original PR by ``@jyn514`` who wrote https://github.com/rust-lang/rust/pull/89346#issuecomment-930129761:
> > add plumbing to pass --check-cfg from rustdoc (do we want this one?)
>
> It would be useful, I think, it catches issues like cfg(doctst) or something (and in general I would like expansion to match rustc as closely as possible).
