* Annotations: Split cleanup into separate queries and deletes to avoid deadlocks on MySQL (#80329)
* Split subquery when cleaning annotations
* update comment
* Raise batch size, now that we pay attention to it
* Iterate in batches
* Separate cancellable batch implementation to allow for multi-statement callbacks, add overload for single-statement use
* Use split-out utility in outer batching loop so it respects context cancellation
* guard against empty queries
* Use SQL parameters
* Use same approach for tags
* drop unused function
* Work around parameter limit on sqlite for large batches
* Bulk insert test data in DB
* Refactor test to customise test data creation
* Add test for catching SQLITE_MAX_VARIABLE_NUMBER limit
* Turn annotation cleanup test to integration tests
* lint
