Thank you for your contribution to Apache Doris.
Don't know what should be done next? See How to process your PR.

Please clearly describe your PR:

What problem was fixed (it's best to include specific error reporting information). How it was fixed.
Which behaviors were modified. What was the previous behavior, what is it now, why was it modified, and what possible impacts might there be.
What features were added. Why was this function added?
Which code was refactored and why was this part of the code refactored?
Which functions were optimized and what is the difference before and after the optimization?

… and `CloudSchemaChangeJob::_convert_historical_rowsets` (apache#50051) Considering the following race situation: 1. thread 1 finish convert historical rowsets before version Y on tablet A and write tmp converted rowset metas on MS 2. thread 2 begins sync_rowsets on tablet A with version Y and get visible rowsets before version Y. 3. thread 1 commit heavy schema change job on MS and turn tmp converted historical rowsets to visible rowsets on tablet Y. 4. thread 1 add converted historical rowset metas to tablet Y's BE local tablet meta and remove all delete bitmaps of new tablet before version Y. 5. thread 2 **add rowsets to tablet Y's BE local tablet meta which overwrites schema change's converted rowsets**. This will cause correctness problem. This PR add a lock to avoid this situation.
