Added new private API for Android and onPause/onResume

On Android the foreground activity can get onPause/onResume
calls. In Nfc code in android we need to know if we are paused
or resumed. And we need to make sure to call disableForegroundDispatch
inside the onPause call and in the main Ui thread. The current
implementiton of applicationStateChanged was not sufficient to
acomplish that.

This patch adds a way to receive those onPause/onResume calls in Qt
with proper timing.
