Back out "Back out "[const_fold] Set requires_grad based on the folded tensor; add device_for_folding option"" (#79696) Summary: This is an un-backout but with a small change to set the default device `device_for_folded_attrs="cuda"` instead of `"cpu"`, which should avoid BC issues for TRT lowering.
