perf: Better order flexible and pinned scheduling
When a task gets scheduled in. We don't touch the cpu bound events so the priority order becomes: cpu pinned, cpu flexible, task pinned, task flexible. So schedule out cpu flexibles when a new task context gets in and correctly order the groups to schedule in: task pinned, cpu flexible, task flexible. Cpu pinned groups don't need to be touched at this time.
