ANDROID: sched: Add parameter to android_rvh_schedule.

Checking whether the ui and render threads are preempted
during frame drawing,then adjusting the prority and core
selection if they are preempted,because we expect the
threads to be executed first.By introducing the
sched_mode parameter, we can check the prev thread
preemption status in the hook, and judging important
threads for executing business logic.
