[quant][fx] Add support for BinarOpQuantizeHandler in backend_config_dict (#74882)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/74882
This PR adds support for ops like add/mul in backend_config_dict, these ops have different
observation_type based on the number of tensor inputs, when number of tensor inputs is 1,
we will share the output observer with input, otherwise we'll have a new observer.
Test Plan:
python test/test_quantization.py TestQuantizeFx
python test/test_quantization.py TestQuantizeFxOps
