servo: Merge #5067 - layout: Implement ordered lists, CSS counters, and `quotes` per CSS 2.1 § 12.3-12.5 (from servo:counters); r=SimonSapin
Only simple alphabetic and numeric counter styles are supported. (This is most of them though.) Although this PR adds a sequential pass to layout, I verified that on pages that contain a reasonable number of ordered lists (Reddit `/r/rust`), the time spent in generated content resolution is dwarfed by the time spent in the parallelizable parts of layout. So I don't expect this to negatively affect our parallelism expect perhaps in pathological cases. Moved from #4544, because Critic. Fixes #4544.
