Pull request: Avoid build crashes when torch.version.xpu doesn't exist and fix Llama4 processor tests

Quick update to #37126 which breaks on my local machine because `torch.version.xpu` doesn't exist. I'm not sure which versions that exists for and which doesn't, but we can just use `getattr()` to avoid crashes in those cases either way.
