* xpu: support xpu backend from stock pytorch (>=2.4)
Fixes: https://github.com/huggingface/transformers/issues/31237
XPU backend is available in the stock PyTorch starting from
version 2.4, see [1]. This commit extends huggingface transformers
to support XPU from both IPEX and the stock pytorch. IPEX is being
tried first.
See: https://github.com/pytorch/pytorch/issues/114842
Requires: https://github.com/huggingface/accelerate/pull/2825

* xpu: enable gpt2 and decision_transformer tests for xpu pytorch backend
Note that running xpu tests requires TRANSFORMERS_TEST_DEVICE_SPEC=spec.py
passed to the test runner:
import torch
DEVICE_NAME = 'xpu'
MANUAL_SEED_FN = torch.xpu.manual_seed
EMPTY_CACHE_FN = torch.xpu.empty_cache
DEVICE_COUNT_FN = torch.xpu.device_count

* Adds `TRANSFORMERS_TEST_BACKEND`
Allows specifying arbitrary additional import following first `import torch`.
This is useful for some custom backends, that will require additional imports to trigger backend registration with upstream torch.
See https://github.com/pytorch/benchmark/pull/1805 for a similar change in `torchbench`.
