Merge branch '25373_SolidAngle_null_vector' of https://github.com/mantidproject/mantid into 25373_SolidAngle_null_vector

- Add normalize() free function to V3D.
- Make the shape-specific solid angle functions free functions in CSGObject. It doesn't make sense to have them as class members.
- General cleanup here and there.
