QStringConverter: fix -Wc++20-compat

GCC 13 warns:

  qstringconverter_p.h:29:6: warning: identifier ‘char8_t’ is a keyword in C++20 [-Wc++20-compat]
     29 | enum char8_t : uchar {};

Fix by calling the replacement qchar8_t (and making it a typedef to
char8_t when the latter is available).

Pick-to: 6.4 6.3 6.2
