[quant][fx] Scope support for call_function in QuantizationTracer (#51086)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/51086
Previously we only supported getting scope for call_module and custom qconfig dict for call_module.
This PR extends the Scope class to record the scope for all node types.
For call_function qconfig if module_name is specified it takes precedence over function qconfig.
Test Plan:
python test/test_quantization.py test_qconfig_for_call_func
