Gets the information about number of messages and buffers in the priority queue. Updates `aInfo` array and adds number of message/buffers in the message queue to the corresponding member variable in `aInfo`.

Same `aInfo` can be passed in multiple calls of `GetInfo(aInfo)` on different queues to add up the number of messages/buffers on different queues.
