MDEV-12179: Per-engine mysql.gtid_slave_pos table.

Browse Source 
Intermediate commit.

On server start, look for and read all tables mysql.gtid_slave_pos* to
restore the GTID position.

Simple test case that moves the data to a new
mysql.gtid_slave_pos_innodb table and verifies that the new table is
read at server start.
