Linux: cefclient: Fix GTK behavior with multi-threaded-message-loop (fixes issue #3087)

Browse Source 
Switch to using g_main_context_default() in MainMessageLoopMultithreadedGtk. As of M86
(https://crrev.com/b960daf4e6) Chromium now creates its own context in MessagePumpGlib so
we can use the default context in cefclient. This is also more "correct" from a GTK usage
perspective. As part of this change all GTK dialogs and callbacks are now executed on the
main thread instead of the UI thread (note that these are the same thread when not using
multi-threaded-message-loop).
