Transition ReferenceClipPathOperation to SVGResource 

This CL replaces the use of SVGElementProxy in
ReferenceClipPathOperation with SVGResource. The main change between the
two is when the element reference is resolved ("when used" versus
"when computed".)

This also, by extension, adds infrastructure for invalidation and other
things required to make SVGResource work.
