Make public non-input/output components in function protected

Some functions use constant variables which are neither input or output, but aren't protected. They should be protected as mentioned by Adrian Pop in !3 (closed) : "The following commits existed among the OpenModelica patches to the library (what we used to use to test ThermoSysPro). Since this Github repository now exists, we should test against it but nothing works without e8c8e0b8."

changed milestone to %ThermoSysPro v4.1

added CI/OpenModelica quick win labels

assigned to @mazurie.baptiste

changed milestone to %ThermoSysPro v4.2

In OpenModelica 1.24 it is seems that simulation fails because of this Traduction Error.

On what model did you have this error ? I will install OM1.24 to test

On ThermoSysPro/Examples/SimpleExamples/TestBend.

To be honest, I had this error on a old ThermoSysPro version (it was just a random test to see if a new VM was properly set, which is not the case, and I do not have git yet), but I do not think we changed anything on this specific point.

created branch 94-make-public-non-input-output-components-in-function-protected to address this issue

DevCom comment: closed since these modifications have been already implemented since the creation of this MR (in the old GitHub).
