NEWT/Android: Full Lifecycle for WindowDriver; Using static ViewGroup; AWTRobotUtil: More tolerant for non AWT env.; Fix adb-launch-*

- NEWT/Android WindowDriver
  - Full Lifecycle, remove refs on closeNative()
  - Respect isFullscreen()
  - Using static ViewGroup if available and surface not ready, allows running from main()

- AWTRobotUtil: More tolerant for non AWT env.
  - Check for NEWT first
  - Only use AWT iff available, which allows running on Android

- Fix adb-launch-*
  - Launch main/junit tests
