USDZ improvements

If you're going to work with a 3D model file in an editor or in code, you almost always want the material names and the structure of the nodes in the scene to stay intact after converting.

From today, converting to and from USDZ preserves these structural details so you can continue working with the new format without having to spend time adjusting the details.
