Add OAT hook calls for more subcommands of ALTER TABLE

Browse Source 
The OAT hooks are added in ALTER TABLE for the following subcommands:
- { ENABLE | DISABLE | [NO] FORCE } ROW LEVEL SECURITY
- { ENABLE | DISABLE } TRIGGER
- { ENABLE | DISABLE } RULE.  Note that there was hook for pg_rewrite,
but not for relation ALTER'ed in pg_class.

Tests are added to test_oat_hook for all the subcommand patterns gaining
hooks here.  Based on an ask from Legs Mansion.
