Objects: make evaluated data runtime storage usable for types other than mesh

This is in preparation of new object types. This only changes mesh_eval, we
may do the same for mesh_deform_eval and other areas in the future if there is
a need for it.

This previously caused a bug in T74283, that should be fixed now.
