drm/i915: Add a hook for making the engines idle (parking) and unparking
In the next patch, we will want to install a callback when the engines (GT as a whole) become idle and similarly when they first become busy. To enable that callback, first rename intel_engines_mark_idle() to intel_engines_park() and provide the companion intel_engines_unpark().
