style: Make scroll-timeline-{name|axis} be a coordinating list property group

Browse source 
Named scroll progress timelines are declared in the coordinated value list
constructed from the longhands of the scroll-timeline shorthand property,
which form a coordinating list property group with scroll-timeline-name as
the coordinating list base property.

In the meantime, we also update its shorthand to match the current spec.
