Summary Fix serializations of scroll-timeline/view-timeline shorthand computed values

To ensure only roundtrip-able values are serialized, the serializations of the scroll-timeline/view-timeline shorthand computed values need to return the empty string when: - The coordinated value list has more than one entry - There is at least one coordinated value that does not have all its properties "set". We should probably also do this for the other coordinated value list shorthands (background, mask, animation, transition), but starting small. (this is based on the discussion in https://github.com/w3c/csswg-drafts/issues/13500).
