Multiple improvements to RwLocks

This PR replicates rust-lang#77147, rust-lang#77380 and rust-lang#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.
