Move 'using MPI_Comm = int' et al to a separate header.

Most of the time we only need declarations of MPI classes (like MPI_Comm) and
not our own utility functions in headers. To this end, we can just put mpi.h (or
our equivalent stub declarations) in a separate header and use that most of the
time.
