rtems: Add rtems_message_queue_construct()
In contrast to message queues created by rtems_message_queue_create(), the
message queues constructed by this directive use a user-provided message buffer
storage area.
Add RTEMS_MESSAGE_QUEUE_BUFFER() to define a message buffer type for message
buffer storage areas.
Update #4007.
