Allow setting each and final prefixes via the API

This issue has been pending for a while, it's time to fix it in the new inst-based interface

• it should be possible to set each in the GUI when inputting parameter values
• it should be possible to set final in the GUI when inputting parameter values
• when changing the unit, the displayUnit modifier should get the each prefix automatically if the parameter is an array, otherwise the model is invalid (OMEdit generates invalid displayUnit modifiers for arrays of parameters #5395).

when changing the unit, the displayUnit modifier should get the each prefix automatically if the parameter is an array, otherwise the model is invalid (#5395).

With PR #11019 the user can set each. OMEdit doesn't automatically add it. We had a discussion about it https://trac.openmodelica.org/OpenModelica/ticket/5405#comment:5 and decided to leave it to user to select it or not.

I agree that the user should have the freedom to choose. That said, I wonder, could we make some analysis on the input and refuse to accept a wrong modifier right away, instead of accepting it and then getting an error from the compiler later on?

I guess it's a fairly typical error for beginners (and not only for them) to forget each when applying a scalar modifier to an array parameter, we should try to prevent this a priori if possible.
