Remove `MPI_All_foo` calls in `VTKHDF5.h`

[garth-wells]

We worked hard to remove all unnecessary MPI_All_foo function call in DOLFINx. We can't let them slip back in.

We would need to figure out how to distribute the various cell types in a consistent order across all processes. The main issue is that in VTKHDF5, there is no global collection of the topology types in the mesh. (It is similar to what in XDMFFile would call a mixed cell type).

For arbitrary order Lagrange meshes, the cmaps are determined by cell_types[i], cell_offsets[i+1]-cell_offsets[i] which is read in as distributed arrays across all processes.
