[Code generation] CVariables should contain a reference to the original port they correspond to
For FMU Generation, it would be nice if CVariables would contain a
reference to the original model element they correspond to, i.e., a
trace to the element they come from.
Can be null if there is none.
Same thing for NoVal variables: they would contain a reference to the
CVariable value they are the “NoVal” of.
Change would be in the model: org-fortiss-af3-generator-common-languages-c
