The "reverse map" of corners to faces and points to curves is the same for meshes and curves now. Move it to the offset indices header to reflect this. This unification can go further in the future, but I'd rather wait until the design is clearer for now. Pull Request: https://projects.blender.org/blender/blender/pulls/106570
