Create a new ListenerInfo object where ephemeral ports are populated with their true runtime
values.

In other words, if a port was set to 0, indicating that a random port should be assigned by the
operating system, this function will replace it with the value the operating system actually
chose.

@param getBoundPortCallback  The callback used to correct ephemeral endpoints.

@return A new ListenerInfo object.
