Move some attributes from PositionVoltageLevelLayoutFactory to LayoutParameters

[So-Fras]

• Do you want to request a feature or report a bug? Feature

• What is the current behavior? The PositionVoltageLevelLayoutFactory class has some attributes that would maybe fit in better with the LayoutParameters class.

• What is the expected behavior? Some attributes (feederStacked, removeUnecessaryFictitiousNodes, substituteSingularFictitiousByFeederNode, ...) moved into the LayoutParameters class.

• What is the motivation / use case for changing the behavior? It would be more user-friendly, especially for users who are new to powsybl-diagram to have those parameters in the LayoutParameters rather than in the PositionVoltageLevelLayoutFactory
