PetscSF: support MPI derived data types created with large count

When user created MPI derived data types with large count routines, e.g., MPI_Type_contiguous_c(4, MPI_DOUBLE, &newtype), and passed newtype to PetscSF,
is it legal to decode the datatype with MPI_Type_get_envelope()? The MPI Forum debated but has yet to resolve this issue.

Our approach is to decode the datatype with MPI_Type_get_envelope_c() if available; otherwise with MPI_Type_get_envelope().

But currently we don't really support real big count values, say a type created by MPI_Type_contiguous_c(2^33, MPI_DOUBLE, &newtype).

We could support that, but just see no needs for now. We will error out if this kind of types are given to PetscSF.
