App language change (#1370)

* Add back option to change app langauge

Courtesy of AndroidX/Appcompat
On Android 13, it uses the native methods (at least for now) Also adding locales config file to only list supported languages in android app info's setting

A bit about this for A12 and under, an app restart is needed right now when switching from LTR to RTL or vice versa, not sure if later versions of androidx app compat will change this

* stop using preference context for strings (when possible)

which fixes some of the language issues on a12 and under

* Fixes to timespanfromnow method

now respect set language

* Dont show langauge selector on android 6

it doesn't work so rip

* Filter out unsupported locales in language selector

* appcompat -> 1.6.0-beta01

* Set notifications to use app language

* Add beta tag to language

* Update ExtensionHolder.kt
