Remove MPI1 functionality completely

  This commit removes MPI1 functionality that was removed in
  the MPI 3.0 standard, completely.

  This commit also removes the ability to configure with
  --enable-mpi1-compatibility configure flag.  Users of these
  removed interfaces should stay at Open MPI v4.x.

  This commit also removes all of the MPI data structures, and
  functions from mpi.h that were removed in the MPI3.0 standard.
  Including the Fortran TKR definitions.
