Fix dynamo issue

[oraluben]

Dynamo use faketensor to trace tensor ops. In some case, the mechanism break compiling with deepspeed.

An example could be found at https://gist.github.com/oraluben/9b8240c2fe482eb4382453d6c97a5f76, to see issues, install deepspeed==0.14.4 instead of my fork

without this PR, llama cannot be compiled.

Detailed explanation:

1. ZeROOrderedDict dynamo use deepcopy to copy tensors, which will call object.__reduce__. When copying ZeROOrderedDict, the default implementation do not copy its _parent_module and will lead to failure.
2. param maybe faketensor and do not have ds_status yet, but during tracing it's ok to just skip the register_external_parameter, it should be done ways before.

torch.compiler.is_compiling() should be better for this case, however there's still issue, presumably on dynamo side (since we have faketensor we're definitely tracing). So keep it for now.

@oraluben - sorry this PR has taken so long to be merged, I think it just needed to have master merged again to get the XPU fixes.
