Removed parameter dynFil in borefield models

[mwetter]

This closes #1885

The entry for the conversion script is

convertModifiers("IBPSA.Fluid.Geothermal.Borefields.BaseClasses.PartialBorefield",
                {"dynFil"}, fill("",0), true);
convertModifiers("IBPSA.Fluid.Geothermal.Borefields.BaseClasses.Boreholes.OneUTube",
                {"dynFil"}, fill("",0), true);
convertModifiers("IBPSA.Fluid.Geothermal.Borefields.BaseClasses.Boreholes.TwoUTube",
                {"dynFil"}, fill("",0), true);

@jelgerjansen @FWuellhorst @nytschgeusen : This is a backward incompatible change that avoids confusion due to a parameter having no effect on the simulation. See notes at #1885

Please raise any objections in the next 2 weeks as this is backward incompatible due to the removal of a parameter.

Fine for AixLib!

[jelgerjansen]

Fine for IDEAS as well!

[nytschgeusen]

Fine for BuildingSystems !

@mwetter : Why didn't you create the conversion script and increased the version number of IBPSA?

[mwetter]

@FWuellhorst : good point. I will make a PR for the update to the conversion script. We increase the number only after an official release and version 4 has not yet been released (https://github.com/ibpsa/modelica-ibpsa/releases) so I left the version number.
