Add OAT hook calls for more subcommands of ALTER TABLE
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 gaininghooks here. Based on an ask from Legs Mansion.Discussion:https://postgr.es/m/tencent_083B3850655AC6EE04FA0A400766D3FE8309@qq.com
