drm/i915: Track runtime spent in closed and unreachable GEM contexts
As contexts are abandoned we want to remember how much GPU time they used
(per class) so later we can used it for smarter purposes.
As GEM contexts are closed we want to have the DRM client remember how
much GPU time they used (per class) so later we can used it for smarter
purposes.
v2:
* Size past runtimes array by uabi class, not internal.
