sched: Consolidate hmp stats into their own struct
Key hmp stats (nr_big_tasks, nr_small_tasks and
cumulative_runnable_average) are currently maintained per-cpu in
'struct rq'. Merge those stats in their own structure (struct
hmp_sched_stats) and modify impacted functions to deal with the newly
introduced structure. This cleanup is required for a subsequent patch
which fixes various issues with use of CFS_BANDWIDTH feature in HMP
scheduler.
