kicad: fix #49089 by adding libraries files

This splits the KiCad package in several derivations:
- original package (main KiCad package)
- internationalization package
- templates
- schematic symbols libraries
- PCB footprints libraries
- 3D models libraries

From these derivations, 2 packages are exposed in top level:
- `kicad` (main KiCad package + all libraries except 3D models)
- `kicad-with-3dpackages` (kicad + all libraries)

The 3D models can also be installed separately with `kicad.packages3d`.
This prevents a new compilation of KiCad, but the user must set the
`KISYS3DMOD` environment variable or option accordingly.
