Don't apply page scale to clipRect if applyPageScaleFactorInCompositor is set to true

If applyPageScaleFactorInCompositor is set to true, webcore should use css coordinates.
As a result, we shouldn't apply page scale to clipRect in RenderLayerCompositor.
Layout tests set the flag to false, so we don't have anything to test against.
