   Split from https://github.com/bitcoin/bitcoin/pull/30997.

   QLocale::nativeCountryName() has been deprecated since Qt 6.6.

   QLocale::nativeTerritoryName() was introduced in Qt 6.2.

   This PR ensures compatibility across all supported Qt versions.

   No behaviour change for the current codebase, which uses Qt 5.

   ---

   This PR can be tested on macOS using the first commit from https://github.com/bitcoin/bitcoin/pull/30997 and Homebrew’s qt package.

   Built this on macOS with qt5.15 and Qt6.7, as well as on Linux Ubuntu with Qt6.4 and Qt6.7, and tested GUI functions related to translations.
