[quant] Enable reference path by default for CopyNodeQuantizeHandler (#73233)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73233
This PR makes CopyNodeQuantizeHandler to always produce reference patterns, and we have
some custom lowering pass to rewrite the reference qunatized patterns to quantized ops
Lowering passes have been implemented previously, we just need to enable the reference path here,
and cleanup the previous code to allow list some of the ops (`check_node`)
Test Plan:
python test/test_quantization.py TestQuantizeFx
python test/test_quantization.py TestQuantizeFxOps
