Automate updating of list of locales for testlocales

This old test program has bitrotted due to not being autogenerated as
part of CLDR updates. Amend qlocalexml2cpp.py to regenerate it and do
such an update. It was still using Qt5's QLocale enum numeric values,
many of which have changed in Qt6. Actually fixing the code so that it
compiles and runs can wait for a later commit.

Inspired by a patch supplied by Kizito Birabwa.
