Summary REGRESSION(r83820): [Qt] Accelerated compositing no longer works in QGraphics...

In r83820, an extra GraphicsLayer was added to the RenderLayerCompositor to contain all other layers, including the new scroll bar layers. The layer never gets a size set, since it's merely a container. This breaks PageClientQGraphicsWidget's assumption that the outermost layer should clip its children. This is already handled by the RenderLayerCompositor's "clip layer."
