[@scope] Let ::From/To return CSSSelector*, improve serialization

This CL prepares for representing the ::From selector as something
that's not a CSSSelectorList (a StyleRule).

This also loses the distinction between an empty list and an absent
list, but I don't think we need this distinction. The only practical
consequence is that during serialization we now drop the "to" part
of the prelude if the associated (forgiving) selector list is empty.
But this serialization is actually better, since it more closely
follows the general CSSOM principle of serializing the shortest
representation.
