Andreas Kling 162412c81a LibWeb: Narrow pseudo-class self invalidation
Only mark an element itself dirty for interaction pseudo-class changes
when matching rules can plausibly match that element. Check every style
scope observing the element, and keep the normal invalidation plan for
descendants and siblings.

Treat pseudo-elements as neutral during the plausibility check so rules
like a:hover::before still invalidate the originating element. Add text
coverage for non-matching hover rules and pseudo-element hover changes.
