Skip processing abort_txn and alloc_write_id_event events if the table is blacklisted

For transactional tables, the event processor is not skipping abort_txn and alloc_write_id_event if the database/table is blacklisted.

This processing is unnecessary and helps to improve event processor lag by skipping abort_txn and alloc_write_id_event events if the corresponding transactional tables are blacklisted.
