In addition to the PackedFunc `"runtime.disco.worker_id"`, which returns the worker ID wrapped in a `ShapeTuple`, this commit adds `"runtime.disco.worker_rank"`, which returns the worker ID without wrapping, and `"runtime.disco.device"`, which returns the device for each worker. The unit test added in this commit simulates loading of model weights through a parameter transformation function.
