score: Add _Thread_queue_Object_name

Add the special thread queue name _Thread_queue_Object_name to mark
thread queues embedded in an object with identifier. Using the special
thread state STATES_THREAD_QUEUE_WITH_IDENTIFIER is not reliable for
this purpose since the thread wait information and thread state are
protected by different SMP locks in separate critical sections. Remove
STATES_THREAD_QUEUE_WITH_IDENTIFIER.

Add and use _Thread_queue_Object_initialize().

Update #2858.
