IO: C++ STL exporter

Browse Source 
There was a C++ STL importer since Blender 3.3, but no corresponding C++ STL exporter. This PR is adding said exporter: taking https://projects.blender.org/blender/blender/pulls/105598 and finishing it (agreed with original author).

Exporting Suzanne with 6 level subdivision (4 million triangles), on Apple M1 Max:
- Binary: python exporter 7.8 sec -> C++ exporter 0.9 sec.
- Ascii: python exporter 13.1 sec -> C++ exporter 4.5 sec.
