Part of #90497.

With this feature, doc_cfg won't pick up items automatically anymore.

@GuillaumeGomez do you mind updating tidy to also look in src/test/rustdoc? It already special cases rustdoc-ui, I don't think adding the new folder should be hard.

Ah so that's what I thought. Adding a check in tidy then.

This PR is beta-nominated. Does it make more sense to just disable doc_cfg on beta? cc @rust-lang/rustdoc for backport discussion

Since this was beta-accepted, I took the liberty of adjusting it to "1.57.0" in #90938. Would someone care to fix that on master as well?

Fix feature annotation in documentation
8798356 
Lots of things in the library are only compiled when certain features
are enabled. However, it is not always clear to the user that in order
to use an item, it will need features x, y, and z, because by default,
this information is not shown.

Fortunately, a feature in `rustdoc` is being developed to provide such
information in the documentation, `doc_cfg`, which is usable right now
in Nightly Rust. To use it, you simply had to activate the feature
somewhere (preferably the crate root) using `#![feature(doc_cfg)]` and
then add `#[doc(cfg(feature = "x"))]` on an item to display that said
item requires the `x` feature. What is awesome about this is that it can
be automatically derived for all `#[cfg(...)]` instances for you.

Unfortunately, it was found out that the auto mode isn't appropriate in
all cases and may sometimes pick the wrong `#[cfg(...)]`. For this
reason, in the "Split doc_cfg and doc_auto_cfg features" pull
request[0], the auto mode has been split into a separate feature. This
commit changes the feature activation line in `lib.rs` to use
`doc_auto_cfg` instead of `doc_cfg`.

Use auto_doc_cfg

This makes it so one doesn't need to manually configure the
