Ojan Vafai 920920310e Delete RenderLayerModelObject.
Merge most of it into RenderBox. Only RenderBoxes can have
layers now. This also meant a bit of code could be cleaned up
since some virtuals (e.g. updateFromStyle) are no longer needed
since they're only called on RenderBoxes.

collectSelfPaintingLayers is the only bit that's moved into
RenderBoxModelObject instead of RenderBox. That's because we
need to be able to recurse down into RenderInlines since they
may contain RenderBoxes that have selfPaintingLayers.
