drm/i915: Split up hangcheck phases
In order to simplify hangcheck state keeping, split hangcheck per engine loop in three phases: state load, action, state save. Add few more hangcheck actions to separate between seqno, head and subunit movements. This helps to gather all the hangcheck actions under a single switch umbrella.
