This PR is a follow to #10408 where support for compile-time checking of features was implemented for rustc.

At the time rustdoc support wasn't yet merged, but now that it has been merged, this pull-request add support for it in the doc and test --doc (doctest) mode.

Thanks!

I think at some point it would be good to get the tests working on Windows.

Add support for rustc --check-cfg well known names and values

This pull-request add support for `rustc` `--check-cfg` well known names and values.

### What does this PR try to resolve?

This pull-request add support for `rustc` `--check-cfg` well known names and values:

- `-Z check-cfg-well-known-names`: `--check-cfg names()` well known names
- `-Z check-cfg-well-known-values`: `--check-cfg values()` well known values

### How should we test and review this PR?

#### Testing

`cargo check -Z check-cfg-well-known-names` and
`cargo check -Z check-cfg-well-known-values`

#### Review

This PR contains one commit that split `features_args` into `check_cfg_args`, add the well known support in it, adds call to that new function and add documentation and test for those new flags.

### Additional information

This was implemented as two new additional flags because it's most likely that these flags will not be stabilize at the same time and also because some of these flags may become the default.

RFC: rust-lang/rfcs#3013
`-Z check-cfg-features`: #10408
`cargo doc` support: #10428
