Rollup merge of #76765 - guswynn:async_return, r=tmandry 
Make it more clear what an about async fn's returns when referring to what it returns

see #76547

This is *likely* not the ONLY place that this happens to be unclear, but we can move this fn to rustc_middle or something like that and reuse it if need be, to apply it to more diagnostics

One outstanding question I have is, if the fn returns (), should I make the message more clear (what about `fn f()` vs `fn f() -> ()`, can you tell those apart in the hir?)

R? `@tmandry`
