Added DIN41612 Type C connector 3D models

Currently the DIN41612 connectors do not have 3D models. I have created 3D model of the DIN41612 Type C connectors from scratch using FreeCAD. I would be great to add them to KiCad.

Edit: The source file PR is over at kicad-packages3D-source!386 (merged).

Edit 2024-01: Added more screenshots showing all connectors
