MDEV-24142: Remove INFORMATION_SCHEMA.INNODB_MUTEXES

Browse Source 
Let us remove sux_lock::waits and the associated bookkeeping.
Starting with commit 1669c8890c
the PERFORMANCE_SCHEMA instrumentation interface is keeping
track of lock waits.

The view INFORMATION_SCHEMA.INNODB_MUTEXES only exported counts
of rw-lock waits.

Also, SHOW ENGINE INNODB MUTEX will no longer export any information
about rw-locks.
