MDEV-29390: Improve coverage for UPDATE and DELETE statements in MTR test suites
Created tests for "delete" based on update_use_source.test For the update_use_source.test tests, data recovery in the table has been changed from a rollback transaction to a complete delete and re-insert of the data with optimize table. Cases are now being checked on three engines. Added tests for update/delete with LooseScan and DuplicateWeedout optimization strategies Added tests for engine MEMORY on delete and update Added tests for multi-update with JSON_TABLE Added tests for multi-update and multi-delete for engine Connect
