Update dummy CREATE ASSERTION grammar
While we are probably still far away from fully implementing
assertions, all patch proposals appear to take issue with the existing
dummy grammar CREATE/DROP ASSERTION productions, so update those a
little bit. Rename the rule, use any_name instead of name, and remove
some unused code. Also remove the production for DROP ASSERTION,
since that would most likely be handled via the generic DROP support.
