704283d6 - Improve `clip_grad_norm` to use torch.linalg.vector_norm (#102429)

Improve `clip_grad_norm` to use torch.linalg.vector_norm (#102429) Done in this PR: - Use `torch.linalg.vector_norm` instead of `torch.norm` - Reduce bandwidth boundary of clip_grad_norm when used with `inf`, ie no need to get the returned tensor after `abs` What I'm slightly unsure: - I don't know if `inf` support `torch._foreach` API Pull Request resolved: https://github.com/pytorch/pytorch/pull/102429 Approved by: https://github.com/lezcano
