editors/abiword: fix build with libc++ 19

Browse source 
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 editors/abiword to fail to compile with clang 19 and
libc++ 19, resulting in errors similar to:

  /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned int>'
    820 |   static_assert(is_same<_CharT, typename traits_type::char_type>::value,
        |                                          ^
  ut_string_class.cpp:1275:41: note: in instantiation of template class 'std::basic_string<unsigned int>' requested here
   1275 |         :       pimpl(new UT_StringImpl<UT_UCS4Char>(*rhs.pimpl))
        |                                                      ^
  /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here
     23 | struct _LIBCPP_TEMPLATE_VIS char_traits;
        |                             ^

This can be fixed by defining `UT_UCS4Char` as `char32_t` instead of
`gunichar`, and patching up a few places where those types are mixed
indiscriminately.
