[Feature]: Add AWQ quantization support for vllm-ascend

[menogrey]

🚀 The feature, motivation and pitch

motivation

AWQ quantization is is a commonly used quantitative method, and there are many quantized models that can be used immediately, such as Qwen. Now vllm-ascend support special quantized model which is quantized by modelslim, but it will take a lot of time to quantize model and we cannot cover all the models if user want to run a quantized model.
