[quant][graphmode][fx] Scope support for call_method in QuantizationTracer (#50173)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/50173
Previously we did not set the qconfig for call_method node correctly since it requires us to know
the scope (module path of the module whose forward graph contains the node) of the node. This
PR modifies the QuantizationTracer to record the scope information and build a map from call_method
Node to module path, which will be used when we construct qconfig_map
Test Plan:
python test/test_quantization.py TestQuantizeFx.test_qconfig_for_call_method
