MDEV-29390: Improve coverage for UPDATE and DELETE statements in MTR test suites

Browse Source 
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
