Description

If I would like to start a Source.actorRef, I need to add an explicit buffer size. In the early stages of development and testing, and later in production monitoring; it would be nice if we could get back the buffer usage information from the actor.

If other thinks this is a good idea, I will PR this.

Contributor guide

Research direction
Investigate the ActorRefSourceActor implementation to understand current buffer management. Look at Akka stream monitoring APIs to see how to expose buffer usage. Consider adding a method like `bufferUsage` to the actor or using existing metrics.
