Description of change

This is a breaking change for MSSQL. MSSQL lacks ability to return affectedRows for update operation without OUTPUT INSERTED.* statement. As this PR fixes that behavior, we are not automatically injecting that statement.

So MSSQL users if need affectedRows count from update, will need to call it with returning: true

Supports disabling OUTPUT INSERTED.* with returning: false

Closes #11203
