Referenced SVG elements in an external resource document match :target

Track which elements are referenced (by <use>) in an external resource document by funneling the lookup through a special function on SVGResourceDocumentContent that creates SVGResourceTarget objects for each (valid) reference and lets the targeted element weakly reference the object. While matching :target, the selector checker will check if the element has a reference to an SVGResourceTarget object and let :target match if it does.
