sci-mathematics/netgen: add 6.2.2204

- OpenMP doesn't seem to be used, remove USE flag
- dev-tcltk/tix doesn't seem to be used, remove dependency
- dev-tcltk/togl is build internal and doesn't use a system togl installation
- Stub generation from pybind11 doesn't currently work in a sandbox, see
  https://github.com/NGSolve/netgen/issues/126
- only depend on sci-libs/metis for USE=mpi
