Parse and serialize scroll-state container queries
https://bugs.webkit.org/show_bug.cgi?id=316536
Reviewed by Tim Nguyen.
Add parsing and serialization for the `@container scroll-state(...)` query
syntax. Four features are recognized inside scroll-state(): scrollable,
scrolled, stuck and snapped, in both the boolean (`scroll-state(stuck)`) and
keyword (`scroll-state(stuck: top)`) forms, gated by the existing
cssScrollStateContainerQueriesEnabled flag.
The features are resolved only inside scroll-state(), mirroring style(), so
they are not matched as bare features. Serialization is handled by the generic
machinery via the stored functionId. Evaluation is a placeholder returning
false; real evaluation against the container's scroll state is a follow-up.
The "<general-enclosed> verbatim" serialization subcase is left as a baked
failure, matching the pre-existing at-container-style-serialization baseline
(a generic media-query parser limitation, not specific to scroll-state).
