Fix torch.compile error for PyTorch v2.3 (#5463)
PyTorch v2.3 throws an error when it tries to compile `iter_params` used
for ZeRO3.
This PR excludes the function from the compilation targets.
After this PR is merged, we can [unpin the torch version for unit
tests](https://github.com/microsoft/DeepSpeed/pull/5459).
