           Summary: [chromium] Draw the root/"non-composited content" in

Currently the root content (what the WK2 compositor calls the non-composited content) is special-cased by LayerRendererChromium and rendered differently from how *LayerChromium or CCLayerImpls are rendered.  We need to somehow render this from the compositor side.

I currently think that the easiest way to do this will be to create a CCLayerImpl of the appropriate type (probably the same type as ContentLayerChromiums have) and during the tree syncing phase set it up at the appropriate point.  From the compositor thread side the "root layer" content can be treated the same way as any other layer, IMO.  This will be clearer when the other issues blocking bug 58799 are resolved.
