TransportationObject model rework

What does this MR do?

Reworks the model of TransportationObject to be able to correctly parse and hold CityGml 3.0 TransportationObjects.
Fixes that some of the Featuretab-Treeviews were being incorrectly rebuilt after a search or search clear.
Fixes that BoundingBoxCalculator ignored geometry data from CityObjects added in 3.16.0.
