smp: Optimize Simple SMP scheduler
Add Thread_Control::is_in_the_air field if configured for SMP. This
helps to simplify the extract operation and avoids superfluous
inter-processor interrupts. Move the processor allocation step into the
enqueue operation.
Add and use _Scheduler_simple_smp_Get_highest_ready(). Add and use
_Scheduler_SMP_Get_lowest_scheduled().
