Reviewed by Yusuke Suzuki.

Invalidation was happening too frequently. Only invalidate when class attribute's value change. Also, instead of invalidating
the all results entries at once, remove specific selector results which were affected by the class attribute change.

To do this, this PR moves the invalidation logic from Node::invalidateNodeListAndCollectionCachesInAncestorsForAttribute to
Element::classAttributeChanged, which has access to space separated class name list.
