Description Tim Nguyen (:ntim) 2023-11-02 11:26:23 PDT 
Spec: https://www.w3.org/TR/css-pseudo-4/#getComputedStyle

WPT:
https://wpt.fyi/results/css/css-highlight-api?label=master&label=experimental&aligned&q=computed


Implementation notes:
Anywhere we take a PseudoId from CSSComputedStyleDeclaration to ComputedStyleExtractor to Element::computedStyle(), etc. we should pass a PseudoElementRequest instead of a PseudoId
CSSComputedStyleDeclaration would also need to convert from a String to a PseudoElementRequest instead of PseudoId

The parser side of this we want to do in CSSSelector::parseStandalonePseudoElement these days.
