style: Implement complex :not().

Browse source 
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.
