drm/i915/scheduler: Boost priorities for flips
Boost the priority of any rendering required to show the next pageflip
as we want to avoid missing the vblank by being delayed by invisible
workload. We prioritise avoiding jank and jitter in the GUI over
starving background tasks.
v2: Descend dma_fence_array when boosting priorities.
