Remove the visit_edges hook from CSS::StyleValue and stop asking CSS properties, descriptors, computed values, and layout nodes to trace through their style values. Style values are refcounted data objects, so they should not be part of the GC graph. Keeping this cleanup separate makes the later layout tree ownership change smaller and easier to review.
