sched: window-stats: legacy mode
Support legacy mode, which results in busy time being seen by governor that is close to what it would have seen via existing APIs i.e get_cpu_idle_time_us(), get_cpu_iowait_time_us() and get_cpu_idle_time_jiffy(). In particular, legacy mode means that only task execution time is counted in rq->curr_runnable_sum and rq->prev_runnable_sum. Also task migration does not result in adjustment of those counters.
