<h3>Log Message</h3>
<pre>Make it possible for MessageReceivers to pass messages to their superclass, and use it for RemoteLayerTreeDrawingAreaProxy
https://bugs.webkit.org/show_bug.cgi?id=126558

Reviewed by Anders Carlsson.

In a message.in file it's now possible to say:

messages -&gt; Subclass : Superclass { ... } and the generated code will
call Superclass::didReceiveMessage().

Use this to have RemoteLayerTreeDrawingAreaProxy pass messages up to
DrawingAreaProxy.
