object_print3d_utils: switch 3D Print Toolbox obj export to use the new exporter

The 3D Print Toolbox addon was using the Python based exporter API,
switch it to use the C++ based obj exporter. This is faster, supports
vertex color attributes, and allows to remove the Python based exporter
some day.
