The list of watch face to build into the firmware is now set by CMake (-DENABLE_WATCHFACES).
Fix SettingWatchFace : convert to index to/from WatchFace when needed.
Restore the default list of apps to compile. The ordering was changed in
the changeset to make the app-list configurable through a CMake-variable
in https://github.com/InfiniTimeOrg/InfiniTime/pull/1928
In the process have one app per line to create the default app list in
CMake. This makes git diffs easer and more readable.
