###  What does this PR do?
Currently, Accelerate has supported ascend npu([see](https://github.com/huggingface/accelerate/pull/1676)).
This PR enables users to leverage the ascend npu for training and inference of 🤗 Transformers models.
For example, you can run the official glue text-classification task using ascend npu with below command:
```bash
export TASK_NAME=sst2
time python -m torch.distributed.run --nproc_per_node 8 run_glue.py \
  --model_name_or_path bert-base-cased \
  --task_name $TASK_NAME \
  --do_train \
  --do_eval \
  --max_seq_length 128 \
  --per_device_train_batch_size 32 \
  --learning_rate 2e-5 \
  --num_train_epochs 3 \
  --output_dir ./output
```

Below are the output logs:

add ascend npu accelerator support. ###  What does this PR do?
Currently, Accelerate has supported ascend npu([see](https://github.com/huggingface/accelerate/pull/1676)).
This PR enables users to leverage the ascend npu for training and inference of 🤗 Transformers models.
For example, you can run the official glue text-classification task using ascend npu with below command:
```bash
export TASK_NAME=sst2
time python -m torch.distributed.run --nproc_per_node 8 run_glue.py \
  --model_name_or_path bert-base-cased \
  --task_name $TASK_NAME \
  --do_train \
  --do_eval \
  --max_seq_length 128 \
  --per_device_train_batch_size 32 \
  --learning_rate 2e-5 \
  --num_train_epochs 3 \
  --output_dir ./output
```

Below are the output logs:
