[quant] AO migration of the `torch/quantization/utils.py` (phase 1) (#64919) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/64919 AO Team is migrating the existing torch.quantization into torch.ao.quantization. We are doing it one file at a time to make sure that the internal callsites are updated properly. This migrates the quantization utilities. ghstack-source-id: 138303325 Test Plan: `buck test mode/dev //caffe2/test:quantization` Reviewed By: jerryzh168 Differential Revision: D30899082 fbshipit-source-id: 85eb38c419e417147e71758b682cd095308dd0c9
