[@scope] Let :scope match shadow hosts

This CL makes it possible once again to @scope again the shadow host.
Fixing this requires several changes:

 - The internal :true pseudo-class must be allowed to match
   the host (the change in SelectorChecker::CheckOne).
   This pseudo-class is prepended to any compound selector
   that contains :scope.
 - Observing the kScopeActivation relation must not count
   as exceeding the scope (the change in SelectorChecker::
   MatchSelector).
 - When matching rules for the shadow host, we must collect rules
   from the universal bucket when :scope may be present.
