    c-family: Have -Wformat-diag accept "decl-specifier" [PR103758]

    I'm tired of seeing

    cp/parser.c:15923:55: warning: misspelled term 'decl' in format; use
'declaration' instead [-Wformat-diag]
    cp/parser.c:15925:57: warning: misspelled term 'decl' in format; use
'declaration' instead [-Wformat-diag]

    every time I compile cp/parser.c, which happens...a lot.  I'd like my
    compilation to be free of warnings, otherwise I'm going to miss some
    important ones.

    "decl-specifiers" is a C++ grammar term; it is not actual code, so
    should not be wrapped with %< %>.  I hope we can accept it as an exception
    in check_tokens.

    It was surrounded by %< %> in cp_parser_decl_specifier_seq, so fix that.

    In passing, fix a misspelling in missspellings.
