    x11-toolkits/mygui: 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 x11-toolkits/mygui to fail to compile with clang 19 and
    libc++ 19, resulting in errors similar to:
    
      In file included from /wrkdirs/usr/ports/x11-toolkits/mygui/work/mygui-MyGUI3.4.2/MyGUIEngine/include/MyGUI_Common.h:12:
      /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned short>'

       y     |                                          ^
      /wrkdirs/usr/ports/x11-toolkits/mygui/work/mygui-MyGUI3.4.2/MyGUIEngine/include/MyGUI_UString.h:213:4: note: in instantiation of template class 'std::basic_string<unsigned short>' requested here

            |                         ^
      /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here

            |                             ^
    
    These can be fixed by using `char16_t` instead of `uint16_t` for the
    `code_point` type, and `char32_t` instead of `uint32_t` for the
    `unicode_char` type.
