Element visibility in parallel VTU
This PR realizes the element visibility in parallel VTU by using vtkGhostType for elements such that
- all regular elements are visible with vtkGhostType=0,
- ghost elements are visible in a unique partition to avoid overlapping.
The element visibility is computed only in partmesh to save computation and communication in running parallel ogs.
