Summary: Previously, enable cudagraph leads to [errors](https://fb.workplace.com/groups/1075192433118967/permalink/1661777797793758/) on AUCMetricComputation. The root cause is that model forward output tensors `predictions`, `labels`, `weights`, and `grouping_keys` got overwritten by the next CUDAGraph replay. This diff fixes the issue by clone these tensors before they are overwritten. The overhead should be small since these tensors only have shape `(n_task, n_examples)`. Differential Revision: D74293458
