Android: Graceful shutdown button in notification for persistent mode

[myxmaster]

Description

This fixes #2501.

#2735 has to be merged first.

Note:
As of Android 13, the OS gives users a way to stop Apps that are running in the background (see https://developer.android.com/develop/background-work/services/fgs/handle-user-stopping). Unfortunately that "Stop" button it not trying any graceful shutdown, but does a hard kill (tested with logging in LndMobileService.java). So we should provide a button on our own notification that will do a graceful shutdown. (Chances are low, but I guess it is not impossible to corrupt the db when doing a hard kill.)

Changes:

• Added button "Shutdown" to Android notification for persistent mode to stop LND gracefully
• Added bridge to use some locale strings on Java layer
  -> translation cache will be updated at app start and when language is changed
• Now using locale strings "LND is running in the background" and "Shutdown" in notification
  -> bridged locale strings are defined in LocaleUtils.ts
• Additionally: removed redundant label "ZEUS" from notification
