Existing UI thread shutdown tasks need to be executed before the UI thread RunLoop is terminated. Those tasks have now been moved to CefMainRunner::StartShutdownOnUIThread and FinishShutdownOnUIThread is now called after the RunLoop is terminated. This fixes a shutdown crash in ChromeProcessSingleton::DeleteInstance. DeleteInstance needs to be called on the UI thread near the end of the shutdown process (after ChromeProcessSingleton::Cleanup is called via PostMainMessageLoopRun).
