Adds support for assigning materials to a tileset. The assigned material overrides the existing glTF material and imagery layers.
CesiumTilesetPrim now inherits from UsdGeomGprim in order for materials to be assigned to it.
In a future PR we may create our own mdl shader nodes that allow people to use the tileset's textures, material properties, and imagery layers in their own materials. This would be needed for more complex materials like texture-based clipping.
There seems to be a Fabric population bug where assigning a material doesn't work unless you enable fabric scene delegate after load. So in order to test this with
cesium.omniverse.dev
you'll need to setapp.useFabricSceneDelegate = false
