Add quadratic tri and quad surface meshing

### 📝 Description of the feature

Hi @waltersma,
It would be great to have midside nodes for tri and quad surface meshing for structural analysis. The projection of corner nodes and midside nodes to the CAD surface would be necessary in this context as well.
