update c++ deployment to support constants/references

[icegood]

It is proposed to update deployment models
https://github.com/COVESA/capicxx-core-tools/blob/master/org.genivi.commonapi.core/deployment/CommonAPI_deployment_spec.fdepl
for "for arguments"
so that generator could add c++ constness of refness (includding && for rvalues) for them. We could optimize calls by avoiding generations of copy constructors for arguments. The absence of properties should lead to backward compatible fdepls.
