Make org.jboss.as.remoting optional from naming extension module; others too if possible

The org.jboss.as.naming module's dependency on org.jboss.as.remoting is only needed if the "service=remote-naming" child resource is used. So it should be made optional with RemoteNamingResourceDefinition registering an additional package.

This is part of an overall effort to eliminate non-optional dependencies on the org.jboss.as.remoting module. Both because depending on extension modules has a code smell but specifically because org.jboss.as.remoting module brings in fairly large dependency tree.

I believe there may be other module dependencies that could be made optional as part of this same work, e.g. org.jboss.remoting and org.wildfly.http-client.naming. Maybe others.
