[@scope] Make '&' in <scope-end> resolve to <scope-start>

Instead of storing the \<scope-start> (i.e. From()) as a CSSSelectorList,
store an empty StyleRule with that same list of selectors.

This allows us to pretend that \<scope-start> is the ancestor rule
for nesting purposes when matching \<scope-end>, as required by spec.

The nesting selector (&) needs to work other places too, but that is
for future CLs to handle.
