[NNC Testing] Randomized loop nest infrastructure (#70410) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/70410 Trying again after #70174 was reverted. Earlier the env variable was read into a static var in C++ causing state to be retained and causing test failures. Static type is removed in this PR.
