Introduce a new GskGpuImageDescriptors object that tracks descriptors for a set of images that can be managed by the GPU. Then have each GskGpuShaderOp just reference the descriptors object they are using, so that the coe can set things up properly. To reference an image, the ops now just reference their descriptor - which is the uint32 we've been sending to the shaders since forever.
