    Fortran: update DATE_AND_TIME intrinsic for Fortran 2018 [PR96580]

    Fortran 2018 allows a non-default integer kind for its VALUES argument if
    it has a decimal exponent range of at least four.  Update checks, library
    implementation and documentation.

    gcc/fortran/ChangeLog:

            PR fortran/96580
            * check.cc (array_size_check): New helper function.
            (gfc_check_date_and_time): Use it for checking minimum size of
            VALUES argument.  Update kind check to Fortran 2018.
            * intrinsic.texi: Fix documentation of DATE_AND_TIME.

    libgfortran/ChangeLog:

            PR fortran/96580
            * intrinsics/date_and_time.c (date_and_time): Handle VALUES
argument
            for kind=2 and kind=16 (if available).

    gcc/testsuite/ChangeLog:

            PR fortran/96580
            * gfortran.dg/date_and_time_2.f90: New test.
            * gfortran.dg/date_and_time_3.f90: New test.
            * gfortran.dg/date_and_time_4.f90: New test.
