Add support for parsing and computing the "scroll-state" value in the container-type CSS property, as defined in CSS Conditional 5. https://drafts.csswg.org/css-conditional-5/#container-type This refactors ContainerType from a simple enum to a struct (following the ScrollbarGutter pattern) to support composite values: - scroll-state (standalone) - size scroll-state - inline-size scroll-state Tests: - css/css-conditional/container-queries/scroll-state/container-type-scroll-state-parsing.html - css/css-conditional/container-queries/scroll-state/container-type-scroll-state-computed.html
