MDEV-10813 - Clean-up InnoDB atomics, memory barriers and mutexes
Clean-up periodic mutex/rwlock waiters wake up. This was a hack needed to
workaround broken mutexes/rwlocks implementation. We must have sane
implementations now and don't need these anymore: release thread is
guaranteed to wake up waiters.
Removed redundant ifdef that has equivalent code in both branches.
Removed os0atomic.h and os0atomic.ic: not used anymore.
Clean-up unused cmake checks.
