DBZ-8340 Commit GTID also for TX playload events

When binlog compression is enabled, events are wrapped inside
`TRANSACTION_PAYLOAD` events and thus GTID set is never updated.
This may cause replay of events when the client thread in interrupted
and started again by keep-alive thread as the new client would start
from the original (initial) GTID set.

Updateing GTID set also for `TRANSACTION_PAYLOAD` events ensures that
GTID set is update also when binlog compression is enabled.
