Feature-gating on closures is broken

[JohnTitor]

If we try to apply #[track_caller] on closures, like:

    pub fn expect_non_local<OtherId>(self) -> Res<OtherId> {
        self.map_id(
            #[track_caller]
            |_| panic!("unexpected `Res::Local`"),
        )
    }

This needs an #![feature(closure_track_caller)], which is normal, but it also needs the feature attributes on the crates that have a caller of that method.

See #96894 (comment) and #96894 (comment) for more details.

TL;DR: In the above PR's situation, that method belongs to rustc_hir but we also have to add the feature attributes to rustc_resolve and librustdoc.

I expected to see this happen: compiles fine with one feature attribute

Instead, this happened: compilation error
