MDEV-6120: When slave stops with error, error message should indicate the failing GTID

Browse Source 
If replication breaks in GTID mode, it is not trivial to determine the GTID of
the failing event group. This is a problem, as such GTID is needed eg. to
explicitly set @@gtid_slave_pos to skip to after that event group, or to
compare errors on different servers, etc.

Fix by ensuring that relevant slave errors logged to the error log include the
GTID of the event group containing the problem event.
