Draft: intel: Add support to protected memory in Xe KMD
What does this MR do and why?
This adds support to protected memory in Xe KMD.
It depends on https://patchwork.freedesktop.org/series/136052/
Marking as a draft because it can only be merged after KMD patches reaches drm-next but this is ready for review.
