[v2,00/16] Introduce Intel PXP

Message

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.

Several major functional changes compared to v1:
- Termination is issued on runtime resume as well.
- Protected objects and contexts are marked as invalid on termination.
  Invalid contexts are reported to userspace via RESET_STATS.
- Trying to flip an invalid objects results in a black frame.

I've done more testing compared to v1 (initial IGTs from Alan will be
hitting the ML soon), but I still haven't stress-tested with userspace
applications, so there might be bugs. I'll make sure to run more testing
and fix everything before merge, but in the meantime I wanted to get
forward with the reviews given that the current tests give me enough
confidence that this isn't completely broken.
