style: Cleanup selector-matching for nested pseudo-elements, match ::slotted correctly when there's no selector before it, and add tests.

Browse source 
D29542 fixed the bogus checks that was making nested pseudo-elements match
author rules. This adds tests and ends up being just a cleanup, though as it
turns out we it also fixes an issue with ::slotted() matched from
Element.matches.
