    OpenMP: Document ompx warnings + add Fortran omx warning [PR106670]

    omp/ompx sentinels are for vendor extensions; as they might be required for
    the correctness of the program, a warning should be printable. This patch
    documents in the OpenMP 5.2 table the existing warnings, including the new
    warning for for fixed source form Fortran.
