0021985: [CEA 715] "Clear mesh data" on a skin mesh without geometry does not preserve the skin mesh

  New behavior:
  - mesh is built on geometry -> "Clear mesh data" removes all nodes/elements
  - mesh w/o geometry (imported, compound, made from scratch) ->
  "Clear mesh data" removes only nodes/elements computed by algorithms
