example/reverse: delete

The reverse bindings allow access to Java and ObjC APIs by importing Java/... and Objc/... package from Go. The gobind tool automatically create the bindings for the API referenced from the packages. The reverse example takes that ability too far, however. It creates a circular dependency from the Android databinding layout files to exported Go types while those same Go types access the Java classes generated by databinding. It works almost by accident, but not for newer Gradle versions. The circular dependencies are bad, but the underlying circular references created by using the reverse bindings this way are worse. I haven't found a satisfactory was to avoid retaining references to Go objects from Java and back without carefully and manually breaking cycles at appropriate times. One might succeed in ObjC where breaking reference cycles are already necessary, but not in Java. The reverse example is a nice technical feat, but promises more than it can deliver. Delete it.
