Change: [Script] Move GSStation::GetOwner to GSBaseStation::GetOwner (#13406)

* Add: [Script] GSBaseStation::GetOwner

Added method for Game Scripts to retrieve the owner of a basestation.

* Cleanup: [Script] Remove ScriptStation::GetOwner

Due to class inheritance, GSStation::GetOwner and GSWaypoint::GetOwner can both reach GetOwner defined at GSBaseStation.
