It turns out `BKE_mesh_copy_parameters` can be called while other tools are running calculations, which meant that it was called at the same time as `armature_deform_coords_impl`. Beause of that, we shouldn't do any freeing (of the old vertex group names) there. Since the materials are copied in the "for_eval" version anyway, it seems to make sense to copy the vertex group name list there also. Fixes T89877, and also the failing `deform_modifiers` test.
