  Fixes #2022, do not resume on Android when surfaceChanged
  
  If the app is in landscape mode and the user presses the power button, a pause
  is followed immediately by a surfaceChanged event because the lock screen
  is shown in portrait mode. This triggers a "false" resume.
  So, we just pause and resume following the onWindowFocusChanged events.
  
  Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before
  blocking the event pump.
