Issue Number: close #33322
Problem Summary: Sometimes, query of ddl job can be empty, which will cause error when execute incremental restore.
What is changed and how it works?
During backup, when we find ddl job with action types about TiFlash or lock/unlock table, we will set the query empty. So we add an action type blacklist, ddl job with action type in blacklist will be ignored. We also ignore ddl job with empty query in case other unexpected situation.
This means that we will ignore ddl jobs about TiFlash or lock/unlock table and ddl jobs with empty query, so they won't cause error by mistake.
