  -----------
  getComputedStyle() should work with functional pseudo-elements like ::highlight()

Reviewed by Antti Koivisto.

This initially landed as 274916 at main but got backed out in 274996 at main
as collateral damage.

This adds parsing support for pseudo-elements with an argument to
CSSSelector::parsePseudoElement(). For now only getComputedStyle()
makes use of it and other callers continue to treat pseudo-elements
with an argument as an error.

To avoid hitting an assert introduced by 274629 at main and also problems
found in debugging where a RenderStyle's pseudoElementNameArgument
would get overwritten this makes
MatchedDeclarationsCache::isCacheable() return false when there is such
an argument.
