style: Implement complex :not().
This fixes the failures in bug 1671573 and just works thanks to the invalidation improvements I did for :is / :where. Added a couple tests for invalidation which is the tricky bit. 001 is a very straight-forward test, 002 is the :is test but with :is() replaced by double-:not(). This also fixes default namespaces inside :is() / :where(), which are supposed to get ignored, but aren't. Added tests for that and for the pre-existing :not() behavior which Chrome doesn't quite get right. Differential Revision: https://phabricator.services.mozilla.com/D94142
