Update the list of country names to the current names in iso-codes
(as output by isoquery -c).
The motivation is updating the name of Czechia as a followup to
https://git.reviewboard.kde.org/r/129644/
As suggested by Albert Astals Cid, fixing the name in i10n is not
enough:
country names are hardcoded in many places and they need to be fixed
separately.
REVIEW: 129691
Instead of an hardcoded list of translations of country names, look
them up in the iso_3166 domain, provided by iso-codes. The names of
countries are changes to their ISO 3166 versions in iso-codes.
Look for iso-codes in cmake, but just as indication of it as runtime
dependency.
