fortran/use-mpi-f08: revamp constant declarations

Просмотр исходного кода 
In order to work around an issue with flang based compilers,
avoid declaring bind(C) constants and use plain Fortran parameter
instead.

For example,
type(MPI_Comm), bind(C, name="ompi_f08_mpi_comm_world") OMPI_PROTECTED :: MPI_COMM_WORLD
is changed to
type(MPI_Comm), parameter :: MPI_COMM_WORLD = MPI_Comm(OMPI_MPI_COMM_WORLD)

Note that in order to preserve ABI compatibility, ompi/mpi/fortran/use-mpi-f08/constants.{c,h}
have been kept even if its symbols are no more referenced by Open MPI.
