cssnode: Implement the style cache

Browse Source 
This essentially copies the previous cache implementation. With one
caveat: It is now attached to and maintained by the CssNode, not by the
CssStyle.

And this is important because styles may be reused in incompatible
situations which would cause cache collisions and lead to broken CSS in
weird situations.
