Qt Quick 3D progressive loading for fast loading of 3D scene

Loading the mesh files all at once is performance overkill
 
•Loading the mesh first and then progressively loading/compiling the materials/textures and HDR maps.
•This would be the default for editing, so scenes show up fast
•The impact on tooling would be high, since initial load time would be improved a lot

This should be a global option that allows progressive loading on any scene.
