Enable ipex xpu op

[jiqing-feng]

1. update dockerfile: I installed the current repo in the dockerfile. This docker file will not introduce any cuda libs! I am not in favor of using docker-compose as the absolute path may be changed in the future. We'd better have a dockerfile that includes all our needed libs, so we can just build and run this dockerfile.
   BTW, I didn't see any bnb_intel path which is in the entrypoint and docker compose yaml file.
2. Enable ipex op for cpu and xpu.

It could pass all transformers tests
