feat: Coordinate converter returns Pose

This change is part of resolving gt-gen-core#12 (closed).

When converting poses from the scenario to the world coordinate system currently the orientation is calculated in a second step using only the xyz world position where the information about the specified lane is already lost: https://gitlab.eclipse.org/eclipse/openpass/openscenario1_engine/-/blob/main/engine/src/Conversion/OscToMantle/ConvertScenarioPosition.cpp#L54

If there are overlapping lanes, then the orientation cannot be calculated correctly. Therefore the information about the lane orientation in world coordinates shall already be provided when the xyz world position is retrieved from the map engine.
