feat: intel xpu register

[avik-pal]

we should really be doing a jll, but for the time being...

On my laptop I have both Nvidia and Intel GPUs, I'm curious to see how this would work 😅

That is same as my setup. This should ideally just register both the intel and nvidia gpus with reactant but use nvidia GPU by default unless we do Reactant.set_default_backend("sycl").

Can confirm that even the python intel-extension-for-openxla doesn't ship with all the required libraries. But installing the support_jll and loader_jll gets us all the ones needed there
