[BUG] Skip WholeGraph Tests if GPU PyTorch Unavailable

[alexbarghi-nv]

Skips WholeGraph tests if GPU PyTorch is not available. Required to get tests passing on ARM. In the future, we should move all WholeGraph-dependent code, as well as the bulk sampling API, into cugraph-gnn so these errors do not continue.

Thank you!

For both the title and description, I think you mean "GPU PyTorch" not "CPU PyTorch", right?

Yes, I just corrected it.

I think we will resolve these sorts of issues for good with #4822

This missed 24.12, retargeting it at 25.02.

Looks good

[jameslamb]

Re-targeting to branch-25.02 introduced some conflicts in the history, I rebased and force-pushed on this branch to resolve those.

Looks like we still need review from @KyleFromNVIDIA

We don't, my review was enough for ci-codeowners / packaging-codeowners. I just removed Kyle from the list for clarity.

We need a cugraph-python-codeowners approval.

@jameslamb you're right, sorry. Let me get someone from our team to review.

LGTM. I wonder if we should start using pytestmark though to skip the entire module for these conditions?
