Rollup merge of #71889 - RalfJung:rwlock, r=Amanieu
Explain our RwLock implementation Turns out that [with the latest POSIX docs](https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_rwlock_wrlock.html), our `RwLock` implementation is actually correct. However, we cannot fully rely on that due to bugs in older glibc (fix released in 2016). Update the comments to explain that. I also clarified our Mutex docs a bit and fixed another instance of https://github.com/rust-lang/rust/pull/55865. r? @Amanieu Fixes https://github.com/rust-lang/rust/issues/53127
