    cad/kicad: fix build with libc++ 19
    
    As noted in the libc++ 19 release notes [1], std::char_traits<> is now
    only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
    instantiation for other types will fail.
    
    This causes cad/kicad to fail to compile with clang 19 and libc++ 19,
    resulting in errors similar to:
    
      /wrkdirs/usr/ports/cad/kicad/work/kicad-7.0.2/thirdparty/nanodbc/nanodbc/nanodbc.cpp:261:25: error: implicit instantiation of undefined template 'std::char_traits<unsigned short>'

            |                             ^
    
    The first batch of errors can be fixed by providing a simple `length()`
    function for the `NANODBC_SQLCHAR const*` type. The second batch can be
    fixed by using `std::basic_string<char16_t>` for `utf16string`, and
    adjusting the call to `std::basic_string<char16_t>::append`.
