The GuC-Error-Capture is currently reaching into xe_devcoredump
structure to store its own place-holder snaphot to workaround
the race between G2H-Error-Capture-Notification vs Drm-Scheduler
triggering GuC-Submission-exec-queue-timeout/kill.
Part of that race workaround design included GuC-Error-Capture taking
on some of the front-end functions for xe_hw_engine_snapshot
generation because of the orthogonal debugfs for raw dumps of engine
registers without any job association. We want this to also be handled,
even if indirectly, by GuC-Error-Capture since there is a lot to manage
when it comes to reading and printing the register lists.
However, logically speaking, GuC-Error-Capture node management,
despite being the majority of an engine-snapshot work, is still
a subset of xe_hw_engine_snapshot.
This series intends to re-design the plumbing for future
maintenence and scalability, rearranging the layering
back to what its should be (xe_devcoredump_snapshot owns
xe_hw_engine_snapshot owns xe_guc_capture_snapshot)..
