Auto merge of #54806 - parched:park, r=RalfJung
thread::unpark: Avoid notifying with mutex locked. This means when the other thread wakes it can continue right away instead of having to wait for the mutex. Also add some comments explaining why the mutex needs to be locked in the first place. This is a follow up to https://github.com/rust-lang/rust/pull/54174 I did some tests with relacy [here](https://gist.github.com/parched/b7fb88c97755a81e5cb9f9048a15f7fb) (This PR is InnerV2). If anyone can think of some other test case worth adding let me know. r? @RalfJung
