Move Aspect Model serializer functionality to core Java module

This removes the separate esmf-aspect-model-serializer module. This makes it
possible to use the serializer functionality in other parts of the core Java
module. From a user's point of view, if they use the esmf-aspect-model-starter,
nothing changes.
