score: Remove Thread_queue_Queue::operations field

Remove the Thread_queue_Queue::operations field to reduce the size of
this structure.  Add a thread queue operations parameter to the
_Thread_queue_First(), _Thread_queue_First_locked(),
_Thread_queue_Enqueue(), _Thread_queue_Dequeue() and
_Thread_queue_Flush() functions.  This is a preparation patch to reduce
the size of several synchronization objects.
