Drop source transformation for Elytron subsystem

The Elytron subsystem is still being transformed via the Batavia source transformer. Now that WildFly has migrated to Jakarta EE 10, we should migrate the subsystem itself and remove the module from the source transformer.

At the moment, WildFly Core is producing two flavors of the Elytron subsystem, one based on javax namespace and the other based on jakarta namespace, which is available at jakartaee/elytron-jakarta.
