  [CSS] @scope parsing
https://bugs.webkit.org/show_bug.cgi?id=264498

Reviewed by Antti Koivisto.

This is boilerplate code to add initial
support for the @scope CSS rule and its parsing.

https://drafts.csswg.org/css-cascade-6/#scope-syntax

It also contains a renaming of "parseCSSSelector" to the more exact name "parseCSSSelectorList".
