Cleanup Constraint metamodel
The following metaclasses in base.ecore are related to classes in kernel.ecore. In this ticket, the implementation should be cleaned up (e.g., by moving these classes to the kernel and writing model migrators if needed, or at least by documenting the design choice):
Also, org.fortiss.tooling.base.compose.ConstraintInstanceContainerCompositor should be checked (currently unused, at least in AF3, but see other products derived from kernel mentioned in #2708 (closed)).
