c3570fd9 - fx quant: preserve node stack trace throughout prepare and convert (#70757)

fx quant: preserve node stack trace throughout prepare and convert (#70757) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/70757 This is an initial PR on a way to preserve stack traces throughout FX graph mode quantization. It preserves the stack traces for ops for all of the quantize handlers. A future PR will add stack traces for dtype transitions. Test Plan: ``` python test/test_quantization.py TestQuantizeFx.test_stack_trace_preserved ``` Note: the above only tests a single case. In a future PR, once we expand coverage, we can expand the utility functions to check for stack traces on all tests. ``` python test/test_quantization.py TestQuantizeFx.test_stack_trace_preserved ``` Imported from OSS Differential Revision: D33432485 D33432485 Reviewed By: jerryzh168 Pulled By: vkuzo fbshipit-source-id: 56c56850393132487430a850fa1def826a9c39c0 (cherry picked from commit c11155b31eb9d228380501860f522a8c89eb2040)
