Convert MPI error type to PETSc error with string message for all MPI calls

Now PETSc examples will ONLY return PETSc error codes and never MPI error codes directly so we can understand and post-process their
errors better.

The test harness will now automatically retry tests that fail with MPI, this may help with Intel MPI that produces
seemingly random failures.

PetscSection: refactor closure permutations to enable multiple depths

PetscSectionGetClosurePermutation(), PetscSectionSetClosurePermutation(), and
PetscSectionGetClosureInversePermutation() all require a new argument depth and
the getters require closure size to be specified by the caller. This allows
multiple closure permutations to be specified, e.g., for mixed topology meshes
and boundary faces.
