dbr quant: stop overridding tensor getters (#70115)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/70115
This PR turns off DBR quant __torch_function__ overrides on
tensor attribute getters such as `x.dtype`. This should help
with making the debug logs more readable, and reduce framework
overhead.
Test Plan:
```
python test/test_quantization.py TestQuantizeDBR
```
