This PR adds initial cube (array) support. Depending on how the texture is used a different image view is created. When used as a framebuffer attachment only a single side of the cubemap is attached. The image view is attached as a 2d texture array. When used as a shader resource the image view is a cubemap. Also adds test cases to test both scenarios.
