Expose RWLocks for fast high read locks

[joshring]

Currently we have the Posix family of functions pthread_rwlock_init ... pthread_rwlock_*

The windows equivalent: https://learn.microsoft.com/en-us/windows/win32/sync/slim-reader-writer--srw--locks

AcquireSRWLockExclusive AcquireSRWLockShared InitializeSRWLock ReleaseSRWLockExclusive ReleaseSRWLockShared SleepConditionVariableSRW TryAcquireSRWLockExclusive TryAcquireSRWLockShared

If we can add the Windows family we can then create a more general abstraction?

I would be interested to look at this later on
