LibWeb: Match styles for pseudo-elements
Since each selector can only have zero or one pseudo-element, we match against it as a separate step, before matching the rest of the selector. This should be faster, but mostly I did this because I could not figure out how else to stop selectors without a pseudo-element from matching the pseudo-element, eg so `.foo` styles don't affect `.foo::before`.
