ImageIndex: Consolidate layer/cube face. In terms of the Texture or Image resource, a cube face refers to a layer of a 2D texture. This layer has a special meaning for cube textures, but it is represented as a layer with a layer index. Cube array textures are no different, they just use a different indexing scheme for the array layers. This also cleans up the ImageIndex helper to have a class structure with private data, and cleans up a few cases to use generic Make functions and iterators where they were setting properties of the index directly. This will make it easier to have ImageIndexes address entire levels of a Cube map in the future, and makes the layer count logic in Vulkan cleaner.
