Laszlo Agocs 1f267b7e6d rhi: Add render-to-cubemap manual test
What's more, demonstrate two types of rendering to a cubemap:
one by one to each face, and by attaching all faces as color
attachments in one go.

Both are used by Qt Quick 3D in connection with shadows, so this
proves that the same is possible to implement with QRhi.
