[Quant][fx] Define native backend_config_dict for linear and conv (#74636)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/74636
This commit changes how quantization patterns for linear
and conv are set up in prepare. Previously, these were set up
through ConvReluQuantizeHandler and LinearReLUQuantizeHandler.
After this commit, however, these were set up through the
corresponding entries in the native backend_config_dict,
rendering the above quantize handlers no longer necessary.
In future commits, we will do the same for the remaining ops.
Test Plan:
python test/test_quantization.py TestQuantizeFx
python test/test_quantization.py TestQuantizeFxOps
