PXP (Protected Xe Path) is an i915 component, available on
GEN12+, that helps to establish the hardware protected session
and manage the status of the alive software session, as well
as its life cycle.
Lots of minor changes and fixes, but the main changes in v3 are:
- Using a protected object with a context not appropriately marked does
no longer result in an execbuf failure. This is to avoid apps
maliciously sharing protected/invalid objects to other apps and
causing them to fail.
- All the termination work now goes through the same worker function,
which allows i915 to drop the mutex lock entirely.

I updated the Mesa MR to use this new version :
- Iris: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8092
- Anv: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8064
No issue with this current iteration :
