Simplify the locking and access of lock hash tables

Details

    Description

      The LockGuard and LockMultiGuard in MDEV-20612 should be a step to the right direction, replacing lock_sys.mutex with a combination of lock_sys.latch and a hash table mutex. However, we could improve performance further if we first computed the start address of the hash table bucket chain and then derived the address of the hash table mutex from that.
