Fix broadcast_all crashing on Tensor-likes (#48169)
Summary:
This ensures Tensor-likes that implement `__torch_function__` are properly handled by `torch.distributions.utils.broadcast_all`. See Issue https://github.com/pytorch/pytorch/issues/37141 .
In this implementation, Number's will not be cast to the dtype of Tensor-likes.
