Fixed Skipping Logic in ProcessGroupNCCLErrors tests (#42192)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/42192
This PR fixes the complicated skipping logic for ProcessGroupNCCLErrors Tests - it correctly logs the reason for skipping tests when GPUs are not available or the NCCL version is too old.
This is part of a broader effort to improve the testing of the ProcessGroup and Collectives tests.

Test Plan: Tested on devGPU and devvm. Tests are run correctly on GPU and skipped on CPU as expected.
