support for vertex parenting in object mode for object types which support it (mesh, lattice, curve, surface)

previously this had to be done one by one.

both single and triagle vertex parents can be made, selected based on distance to the verts.

Developer notes:
- looks like this was old TODO, enums existed but weren't used.
- only meshes currently support using.
- added BKE_object_as_kdtree(), may come in handy for similar cases.
