run phi3-mini on AMD NPU

1. If no ```phi3_mini_awq_4bit_no_flash_attention.pt```, use awq quantization to get the quantization model.
2. Put modeling_phi3.py in this repo into the phi-3-mini folder.
3. Modify the file path in the run_awq.py
4. run ```python run_awq.py --task decode --target aie --w_bit 4```

As the quantization of phi-3, may refer to https://github.com/mit-han-lab/llm-awq/pull/183

PS: The performance is similar to that on CPU(7640hs).
