Rollup merge of #118504 - compiler-errors:must-use, r=WaffleLapkin ...

Enforce `must_use` on associated types and RPITITs that have a must-use trait in bounds

Warn when an RPITIT or (un-normalized) associated type with a `#[must_use]` trait in its bounds is unused.

This is pending T-lang approval, since it changes the semantics of the `#[must_use]` attribute slightly, but I think it strictly catches more strange errors.

I could also limit this to just RPITITs, but that seems less useful.

Fixes #118444
