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.

Fix DM issues in SplitTS

- Revert the commit feb1c02f. It causes the multirate ODE examples to fail. In addition, this commit seems unnecessary since the subts DM is set up in TSMPRKSetSplits() for MPRK and in TSSetUp_RK_MultirateSplit() for MRK.
- Clean up serveral multirate examples and add them to tests.
