feat(PMInstaller): wait for uninstalls & fix PM session lifecycle bugs

- Support waiting for package uninstallation results - Make DowngradeCheckStep wait for uninstall rather than erroring - Relaunch PackageInstaller user action intents infinitely until result received (Workaround of bug on some ROMs where dismissing the PI dialog by clicking outside wouldn't invoke the callback with STATUS_FAILURE_ABORTED) - Make PMIntentReceiver & PMResultReceiver non-exported to keep intents from leaking to other apps - Handle uncaught exceptions thrown in the aforementioned receivers by returning the result back to the app (or logging) to prevent crashes
