sched: remove csection and reduce the interrupt disabling time in sched_[un]lock

Browse source 
reason:
1 Accelerated the implementation of sched_lock, remove enter_critical_section in sched_lock and
only enter_critical_section when task scheduling is required.
2 we add sched_lock_wo_note/sched_unlock_wo_note and it does not perform instrumentation logic
