drm/xe/debugfs: Expose per-engine idle status

Browse source

Extend the existing "hw_engines" debugfs to iterate over all hardware
engines and dump their idle state: whether the engine pipe is idle or
busy, whether C6 entry is allowed, and (where available) the forcewake
request status.

v2: Use existing debugfs (Matt Brost)
v3: Rename macro (Vinay)
