Clean up RenderLayerBacking code that looks for the body
https://bugs.webkit.org/show_bug.cgi?id=39502

Source/WebCore:

Reviewed by Dave Hyatt.

Consolidate code that propagates the <body> background to the
root, adding a utility method on RenderObject that is called
by RenderBox and RenderLayerBacking.

Removed an unused method in RenderLayerBacking.

The compositiong changes are not testable, since rendererBackgroundColor()
is only used by fullscreen at present.
