[cecilia] Provide a check-adl compilation command
It would be useful a "check-adl" compilation command (to the Cecilia Launcher and to the related higher level facilities, as "ceciliac" and the "maven-ceciliaadl-plugin") in order to just verify that a given Cecilia application ADL architecture is valid, without dealing with any code generation and compilation.
It would thus just invoke the full Cecilia Loader chain, reporting errors if it is invalid (ie. bindings missing, artifact file not found, ...).
