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
```
