Successfully built torch with both Nvidia and Intel GPU support

[CarlGao4]

I've just successfully built torch with both Nvidia and Intel GPU support:

About the versions:

(torch 2.1.0 release and ipex 2.1.30+xpu)

I'll pack CUDA+MKL from the next version.

I did a little bit hacking (or upgrading, actually) to achieve this. I copied some of the codes from torch 2.2.2. Files including /torch/cuda/__init__.py /torch/cuda/streams.py torch/_inductor/config.py.
