score: _Thread_queue_Flush() parameter changes

Change _Thread_queue_Flush() into a macro that invokes
_Thread_queue_Do_flush() with the parameter set defined by
RTEMS_MULTIPROCESSING. For multiprocessing configurations add the
object identifier to avoid direct use of the thread wait information.

Use mp_ prefix for multiprocessing related parameters.

Rename Thread_queue_Flush_callout to Thread_queue_MP_callout since this
type will be re-used later for other operations as well.
