MDEV-20612: Replace lock_sys.mutex with lock_sys.latch
For now, we will acquire the lock_sys.latch only in exclusive mode,
that is, use it as a mutex.
This is preparation for the next commit where we will introduce
a less intrusive alternative, combining a shared lock_sys.latch
with dict_table_t::lock_mutex or a mutex embedded in
lock_sys.rec_hash, lock_sys.prdt_hash, or lock_sys.prdt_page_hash.
