Split UI thread shutdown into before and after stages (see #3609)

Browse Source 
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).
