  1. mpi/misc: Move GPU query support implementation to MPIR layer 

    There is a use-case for this function to be called during MPI init in
support the memory allocation kinds feature. Add an MPIR function which
bypasses the MPI initialized check.

  3. test/mpich: Update memory alloc kinds test 

    With the addition of CUDA kinds as supported memory allocation kinds, we
need to tweak our verification logic slightly. As of today, unless
requested by the user, MPICH will always add GPU-related memory kinds at
the end of the supported string. Therefore we just check our expected
string against the beginning of the returned value using strncmp.
