android-luajit-launcher refactor (#6821)

- Lcd devices won't use the SurfaceView, just the good old native content/window (except AndroidTv and ChromeOS)
- All android dialogs will be presented with Material Design on recent devices.
- Added an option to device settings to manage application battery optimization.
- Permissions that require the user to go to a settings page will be presented with a native android dialog.
- bump android-luajit-launcher

- Changes under the hood: koreader/android-luajit-launcher#257
