Qt defines StateLocation (location for the *staterc files) as `C:/Users/<USER>/AppData/Local/<APPNAME>/State`Kleopatra (and other KDE apps) shall store the *staterc files below %LOCALAPPDATA% instead of below %GNUPGHOME%.
Implementation hints:
* Qt defines StateLocation (defaults to `C:/Users/<USER>/AppData/Local/<APPNAME>/State`)
but KF uses AppDataLocation instead, which is `C:/Users/<USER>/AppData/Roaming/<APPNAME>`* We re-define StateLocation (and GenericStateLocation) in the qt.conf we install
* kconfig uses AppDataLocation (defaults to `C:/Users/<USER>/AppData/Roaming/<APPNAME>`) for the state config files (on not-Linux)
Make KF use the location defined in QT.Plan:
* Remove re-definitions of StateLocation (and GenericStateLocation) from our qt.conf
* Patch kconfig to use StateLocation instead of AppDataLocation for state files
* Migrate state files from pre-KF6 location to new location
* Try to upstream the kconfig patch
