This PR replicates #77147, #77380 and #84650 on RWLocks :

  • Split sys_common::RWLock in StaticRWLock and MovableRWLock
  • Unbox rwlocks on some platforms (Windows, Wasm and unsupported)
  • Simplify RwLock::into_inner

Notes to reviewers :

  • For each target, I copied MovableMutex to guess if MovableRWLock should be boxed.
  • A comment says that StaticMutex is not re-entrant, I don't understand why and I don't know whether it applies to StaticRWLock.
