Support Android's per-app language setting

[Korb]

Is your feature request related to a problem? Please describe.
A single mechanism for changing locale for all applications on a device, making life easier for both users and developers/translators.

Describe the solution you'd like
The language selector in the app is kind of a legacy UI - now that Android supports per-app language settings (System Settings → System → Languages → App languages), we should support that and eventually get rid of the in-app language selector.

Describe alternatives you've considered
Use the outdated mechanics of changing the application language through the interface of the application itself. The method is inconvenient because each application hid this setting in its own branch of the tree of its settings.

@Korb Thanks for opening the issue, we will implement this feature in our application as it gives access to the user to control the localization of the app from system settings(From there they can directly change the application language).

We should support that and eventually get rid of the in-app language selector.

We can not remove the in-app language selector since the per-app language setting is only available for Android 13 and above devices. So below Android 13 devices we still need this functionality. Also, the user should have control in the application to change the app language.
