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.

Changes from v6:

- reworked object invalidation to be based on PXP instance instead of
  lists, so we can drop the locking (Daniel).

- just keep a wakeref while a protected context is around (Daniel).

- don't add a new flag to RESET_STATS, just increase the guilty count as
  if we had a hang (Daniel).

- add kerneldoc (Daniel). Added it all in one go at the end so it is
  easier to review.

- change location for the display blackscreen check (Juston).

- fix an issue with pxp component removal.

Tested with: https://patchwork.freedesktop.org/series/87570/
