Support SmoothQuant for ORT static quantization (#16288)
### Description
Support SmoothQuant for ORT static quantization via intel neural
compressor
> Note:
Please use neural-compressor==2.2 to try SmoothQuant function.
### Motivation and Context
For large language models (LLMs) with gigantic parameters, the
systematic outliers make quantification of activations difficult. As a
training free post-training quantization (PTQ) solution, SmoothQuant
offline migrates this difficulty from activations to weights with a
mathematically equivalent transformation. Integrating SmoothQuant into
ORT quantization can benefit the accuracy of INT8 LLMs.
