Fixes two issues in camera navigation:
- Unintuitive camera rotation
- Wrong center point when zooming in/out and rotating
See https://github.com/qgis/QGIS-Enhancement-Proposals/issues/215
This PR employs the following changes:
- The zoom in functionality will zoom in towards the real 3D position of an object in the scene instead the camera view center point used previously.
- The rotation will use the real clicked 3D position of a pixel as well instead of the camera view center point.
- The press and drag behaviour is improved to shift the map in real 3D coordinates instead of some arbitrary measurement (you can see the clicked pixel following the cursor instead of drifting away).

for specifying terrain layers to render
Previously the one method was used for both, which made it very
difficult to have a different set of layers used for terrain
generation vs 3d entity generation (you had to manually create a map
theme, which is very messy)
If enabled, shows a sphere at light source origins, allowing easier repositioning
and placement of light sources relative to the scene contents
Fixes#37726
