    openmp: Fix up handling of kind(host) and kind(nohost) in ACCEL_COMPILERs
[PR103384]

    As the testcase shows, we weren't handling kind(host) and kind(nohost)
properly
    in the ACCEL_COMPILERs, the code written in there is valid for the host
    compiler only, where if we are maybe offloaded, we defer resolution after
IPA,
    otherwise return 0 for kind(nohost) and accept it for kind(host).  Note,
    omp_maybe_offloaded is false after IPA.  If ACCEL_COMPILER is defined, it
is
    the other way around, but also we know we are after IPA.
