MDEV-12179: Per-engine mysql.gtid_slave_pos table
Intermediate commit.
Implement status variables to aid the DBA in determining the need
and/or effectiveness of the per-engine mylsq.gtid_slave_pos feature:
transactions_multi_engine
Number of transactions that changed data in multiple (transactional)
storage engines.
rpl_transactions_multi_engine
Number of replicated transactions that involved changes in multiple
(transactional) storage engines, before considering the update of the
mysql.gtid_slave_posXXX table.
transactions_gtid_foreign_engine
Number of replicated transactions where the update of the
mysql.gtid_slave_posXXX table had to choose a storage engine that did not
otherwise participate in the transaction.
