Can we get XPU Nightlies?

[Jack-Khuu]

I'm working with @jenniew over on torchchat to add XPU support for the Intel side: pytorch/torchchat#1361
And we noticed that tune doesn't have XPU nightlies, so we have to default back to 0.3.1.

Ask: Is there appetite for/can we get XPU nightlies?

There was a request around this quite a while back: #999. A community contributor put up a draft PR for enabling this but we never followed up: #1280. There is still work to make sure our recipes support XPU and we have CI that tests XPU before we can get XPU nightlies.

Do we spin up XPU versions for major releases (e.g. 0.4.0)? If so we may lean on that temporarily from the torchchat side so versions don't diverge too far from main
