Andreas Kling bbf67faa95 LibWeb: Add CSS rule buckets for pseudo elements, and for :root ...

If a selector must match a pseudo element, or must match the root
element, we now cache that information in the MatchingRule struct.
We also introduce separate buckets for these rules, so we can avoid
running them altogether if the current element can't possibly match.

This cuts the number of selectors evaluated by 32% when loading our
