[fenix] For https://github.com/mozilla-mobile/fenix/issues/17869 - Start the Android Keystore experiment

Browse Source 
Only on API 23+ (minimum Android version needed for SecureAbove22Preferences)
and only if enabled by a Nimbus experiment.

The Nimbus experiment will have the key `fenix-android-keystore` and use the
default branches - "control" and "treatment".
