    Fortran: restrictions on integer arguments to SYSTEM_CLOCK [PR112609]

    Fortran 2023 added restrictions on integer arguments to SYSTEM_CLOCK to
    have a decimal exponent range at least as large as a default integer,
    and that all integer arguments have the same kind type parameter.

    gcc/fortran/ChangeLog:

            PR fortran/112609
            * check.cc (gfc_check_system_clock): Add checks on integer
arguments
            to SYSTEM_CLOCK specific to F2023.
            * error.cc (notify_std_msg): Adjust to handle new features added
            in F2023.
            * gfortran.texi (_gfortran_set_options): Document
GFC_STD_F2023_DEL,
            remove obsolete option GFC_STD_F2008_TS and fix enumeration values.
            * libgfortran.h (GFC_STD_F2023_DEL): Add and use in
GFC_STD_OPT_F23.
            * options.cc (set_default_std_flags): Add GFC_STD_F2023_DEL.
