The default savepath on macOS used to be in the user Document folder. However ScummVM requires special permission to access that folder, and if the user denied it, this caused various issues. This implement ticket #11428. This commit also contains migration code that that old configs that used the default path are set explicitly to use the old default path. So the change of savepath will only be for new users.
