Workaround for back arrow being stuck on screen
- Whenever we defer the cleanup of the back gesture, schedule a failsafe
to clean up the window if it's not handled properly. We'll enable
this failsafe for sc-dev and disable it for further investigations
post sc-dev
- Dump additional info for the nav bar window so we can narrow down
the issue post sc-dev
Bug: 190778197
Test: Can't repro the initial issue, so artificially trigger it to verify failsafe
Test: adb shell dumpsys activity service SystemUIService
