Fix T67385: Bind in Laplacian Deform Modifier with new vertex group in Edit Mode crashes Blender.

Main issue in that report was that meshes generated from
`mesh_create_eval_final_view()` and the like need some
special freeing handling (as, among other things, they borrow and do not
own their potential editmesh data...).

Factorized that into a helper func also used by
`BKE_object_free_derived_caches()`.
