Rollup merge of #100633 - estebank:must_use_async_fn_return, r=tmandry
Consider `#[must_use]` annotation on `async fn` as also affecting the `Future::Output` No longer lint against `#[must_use] async fn foo()`. When encountering a statement that awaits on a `Future`, check if the `Future`'s parent item is annotated with `#[must_use]` and emit a lint if so. This effectively makes `must_use` an annotation on the `Future::Output` instead of only the `Future` itself. Fix #78149.
