Dimitry Andric 849cc48702 devel/py-Levenshtein: 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 ports using devel/py-Levenshtein 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,
        |                                          ^
  /wrkdirs/usr/ports/devel/py-Levenshtein/work-py311/Levenshtein-0.22.0/src/Levenshtein/Levenshtein-c/_levenshtein.hpp:144:43: note: in instantiation of template class 'std::basic_string<unsigned int>' requested here
    144 | static inline std::basic_string<uint32_t> lev_greedy_median(const std::vector<RF_String>& strings,
        |                                           ^
  /usr/include/c++/v1/__fwd/string.h:23:29: note: template is declared here
     23 | struct _LIBCPP_TEMPLATE_VIS char_traits;
        |                             ^

Unfortunately py-Levenshtein and its embedded copy of rapidfuzz-cpp make
heavy use of the no-longer-existing `std::basic_string<uint8_t>`, so I
had to do quite a lots of search and replace operations, replacing these
with equivalent `std::vector` types.

This is similar to the fixes for devel/rapidfuzz-cpp in bug 281193, and
for devel/py-rapidfuzz in bug 281194.
