macOS: Modernize masking of windows
Instead of masking window blitting via a CGImage mask, we use the window's mask directly to intersect the region that we blit during flushing of the QCocoaBackingStore. This approach also enables masking of child windows. We now also support setting a mask for layer-backed views, by setting a CAShapeLayer as the layer's mask. The window shadow invalidation has been moved out of QNSView, as the view should not be involved in that process. For layer-backed views, the shadow is not invalidated as expected after the initial mask has been set, but this bug has been left as a fix for a later stage as it requires more research.
