score: Add Thread_queue_Control::Lock
Move the complete thread queue enqueue procedure into
_Thread_queue_Enqueue_critical(). It is possible to use the thread
queue lock to protect state of the object embedding the thread queue.
This enables per object fine grained locking in the future.
Delete _Thread_queue_Enter_critical_section().
Update #2273.
