Summary: Add a param in the base parser to set `torch_nccl_enable_timing` variable to `False` by default, and only set it to true if user needed. This value is used only on flight-recorder (for debugging purpose), and significantly affect performance of benchmarking in blocking mode (~30% for small-mid message sizes) if enable Reviewed By: kingchc Differential Revision: D72240605
