Reviewed by Antti Koivisto.

TiledCoreAnimationDrawingArea shouldn't be in the business of groveling around in
RenderView, RenderLayers and RenderLayerBackings for specific layers, so have
FrameView vend those layers as GraphicsLayers.

* Source/WebCore/page/FrameView.cpp:
(WebCore::FrameView::graphicsLayerForPageScale):
(WebCore::FrameView::graphicsLayerForTransientZoomShadow):
* Source/WebCore/page/FrameView.h:
* Source/WebKit/Shared/RemoteLayerTree/RemoteLayerTreeTransaction.mm:
(WebKit::RemoteLayerTreeTransaction::dump const): Use WTFLogAlways() not fprintf().
* Source/WebKit/WebProcess/WebPage/mac/TiledCoreAnimationDrawingArea.mm:
(WebKit::TiledCoreAnimationDrawingArea::updateDebugInfoLayer):
(WebKit::TiledCoreAnimationDrawingArea::layerForTransientZoom const):
(WebKit::TiledCoreAnimationDrawingArea::shadowLayerForTransientZoom const):
(WebKit::TiledCoreAnimationDrawingArea::adjustTransientZoom):
