Rollup merge of #121119 - compiler-errors:async-fn-kind-errs, r=oli-obk
Make `async Fn` trait kind errors better

1. Make it so that async closures with the wrong closurekind actually report a useful error
2. Explain why async closures can sometimes not implement `Fn`/`FnMut` (because they capture things)
