Make propagation final of lifted parameters in Spring (#4407)

* Make propagation final of lifted parameter 'c' in Spring

Fixes #3707.

* Make propagation final of lifted parameter 's_rel0' in Spring

* Make propagation final of lifted parameters in Spring's lineForce component

Even though the modification of lineShapeType is not parameter lifting, it would make little sense to make it non-final when all other modifications are final.

* Make propagation of lifted parameter 'd' final in ModelicaTest example SpringDamperParallel
