Run distributed_test with NCCL_ASYNC_ERROR_HANDLING (#52619)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/52619
Runs this test suite with nccl_async_error_handling enabled. It is the
default to run many distributed training jobs, and can also help catch
errors/hangs in tests more easily. We don't expect any changes in the actual
existing tests since they shouldn't have any hangs.
