Auto merge of #76645 - fusion-engineering-forks:windows-lock, r=kennytm
Small cleanups in Windows Mutex. - Move `held` into the boxed part, since the SRW lock implementation does not use this. This makes the Mutex 50% smaller. - Use `Cell` instead of `UnsafeCell` for `held`, such that `.replace()` can be used. - Add some comments. - Avoid creating multiple `&mut`s to the critical section object in `ReentrantMutex`.
