Utility functions for NavigationServer2D/3D to find missing RID information when working with Server API directly. e.g. from map to regions and agents, from agent or region to map, from region to map and agents and so on .... Requirement to work with NavigationServer API exklusive without SceneTree nodes and when juggling agents and regions between multiple navigation maps.
