cc : Clean up cc clip tree

* Cache the dynamically computed clip and visible rects and use them to calculate clip and visible rects.

* Stop creating clip nodes for render surfaces.

* Delete combined_clip_in_target_space, clip_in_target_space,
  target_effect_id, layer_clipping_uses_only_local_clip,
  layers_are_clipped, layers_are_clipped_when_surfaces_disabled,
  resets_clip from clip node

* Remove the verify_clip_rect_calculations path from tests.
