sched: add execute_tasks() helper function

The execute_tasks() helper is responsible for collectively unblocking all CPUs, calling run_tasks() on BSP CPU and waiting for all AP CPUs untile they are finished. In kernel_main the execute_tasks() is called before test_main() just in case. Currently there are no tasks scheduled before the test_main(). The execute_tasks() called after the test_main() makes sure all APs and the BSP get unblocked and their tasks executed or the states of the CPUs are set to finished.
