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
