drm/i915: include hangcheck action and score in error_state

Browse Source 
Score and action reveals what all the rings were doing
and why hang was declared. Add idle state so that
we can distinguish between waiting and idle ring.

v2: - add idle as a hangcheck action
    - consensed hangcheck status to single line (Chris)
    - mark active explicitly when we are making progress (Chris)
