seems os.environ.get() not working well on windows (#59634) Summary: replace with os.getenv() instead For some reason this was intermittently failing azure pipelines. I can't login to the pipeline itself for debugging but here are 2 examples: [successful](https://app.circleci.com/pipelines/github/pytorch/pytorch/332405/workflows/944609ad-5dcf-49da-984f-26c381d1f16c/jobs/13969059) vs [failed](https://app.circleci.com/pipelines/github/pytorch/pytorch/332518/workflows/21f8a5a6-3b95-432e-be42-ac98008c671b/jobs/13975637) However given the fact that the other common_utils.py exposed constants using `os.getenv()` was working. I am making them consistent.
