Running `cefsimple --enable-chrome-runtime` will create and run a Chrome browser window using the CEF app methods, and call CefApp::OnContextInitialized as expected. CEF task methods also work as expected in the main process. No browser-related methods or callbacks are currently supported for the Chrome window, and the application will exit when the last Chrome window closes. The Chrome runtime requires resources.pak, chrome_100_percent.pak and chrome_200_percent.pak files which were not previously built with CEF. It shares the existing locales pak files which have been updated to include additional Chrome-specific strings. On Linux, the Chrome runtime requires GTK so use_gtk=true must be specified via GN_DEFINES when building. This change also refactors the CEF runtime, which can be tested in the various supported modes by running: $ cefclient $ cefclient --multi-threaded-message-loop $ cefclient --external-message-pump
