cefclient: views: Support window state restore (see issue #3359)

Browse Source 
The cefclient sample app will persist window state across application restart
if run with views, cache_path and persist_user_references enabled.

To test:
1. Run `cefclient --use-views --cache-path=/path/to/cache --persist-user-preferences`
2. Move or resize the window, maximize, minimize, etc.
3. Exit cefclient.
4. Run cefclient again with the same arguments. The previous window state will
   be restored.
