Summary: This diff is a followup of D73474285 and lets other dense optimizers take it the `enable_global_grad_clip` optim config. When `enalbe_global_grad_clip=True` and FSDP1 is used, it would calculate global gradient norm at a cost of extra communication. Next steps: 1. global clipping more generic and work for FSDP2.
