Subject: [PATCH] Adding support for per-app language preferences on Android 13
 and later

Android 13 added the ability to select languages on a per-app basis. Supporting this feature simply requires us to provide a listing of all of the locales supported by the app: https://developer.android.com/guide/topics/resources/app-languages

This change adds a locales_config.xml file to list the locales and references this file in the application manifest
