[PLAT-18442] Disable DDL atomicity check if YSQL is not enabled for the universe

Summary:
Right now we'll attempt to perform DDL atomicity check on the universe even if it's YCQL only unvierse.
And the check fails in above case, obviously.
This diff fixes that by disabling the check in case YSQL is not enabled.

Test Plan:
Create YCQL only universe
Make sure all health checks are successful.
