MDEV-13915: Updates to existing MTR tests

MDEV-13915: STOP SLAVE takes very long time on a busy system

The problem is that a parallel replica would not immediately stop
running/queued transactions when issued STOP SLAVE. This would lead
to long periods to wait for all waiting transactions to finish.

This patch updates a parallel replica to try and abort immediately
and roll-back any ongoing transactions. The exception is with
non-transactional workloads. If any threads have modified any
non-transactional tables, it along with all prior transactions
are executed as well.

MDEV-30620 Trying to lock uninitialized LOCK_parallel_entry

The error was seen by a number of mtr tests being caused
by overdue initialization of rpl_parallel::LOCK_parallel_entry.
Specifically, SHOW-SLAVE-STATUS might find in
rpl_parallel::workers_idle() a gtid domain hash entry
already inserted whose mutex had not done
mysql_mutex_init().

Fixed with swapping the mutex init and the its entry's stack insertion.

Tested with a generous number of `mtr --repeat` of a few of the reported
to fail tests, incl rpl.parallel_backup.
