Support different spatial references for 2D and 3D

Currently, there exists the limitation: 

If both a 2D web map and 3D web scene are configured in the Map component, the 2D web map must also use exactly the same spatial reference as the 3D web scene.

It would be nice, to support different spatial references for the 2D web map and 3D web scene.
