add doc-hidden to exports in attribute prelude

Seems to fix rust-lang/rust#145870, at least temporarily. The underlying problem of course is still there.

r? `@fmease`

Rollup merge of #145573 - veluca93:unsafe-force-target-feature, r=davidtwco 
Add an experimental unsafe(force_target_feature) attribute.

This uses the feature gate for https://github.com/rust-lang/rust/issues/143352, but is described in https://github.com/rust-lang/rfcs/pull/3820 which is strongly tied to the experiment.

Rollup merge of #145500 - JonathanBrouwer:must_use_target, r=jdonszelmann 
Port must_use to the new target checking

This PR ports `must_use` to the new target checking logic
This also adds a tool-only suggestion to remove attributes on invalid targets, as to not immediately undo the work of https://github.com/rust-lang/rust/pull/145274
