WIN32: Fix infinite loop when converting from utf32

Because of how cyrilic transliteration and UTF-32 is handled on
Windows, it was unfortunately possible to get into an infinite
loop of conversions. The string would get converted to UTF-32
when transliterating, but because windows backend conversion
cannot convert from UTF-32, it would use Common::Ustr to convert
it to UTF-8, which would again get converted to UTF-32 when
transliterating and so on.
