Always send _NET_WM_FRAME_DRAWN for newly created windows
Send a _NET_WM_FRAME_DRAWN for each newly created window, as required by the specification. This avoids a race where a window might be created frozen but already unfrozen by the time we first see fetch the counter value. Remove a duplicate call to meta_compositor_set_updates_frozen() which was called before the MetaWindowActor is created and hence did nothing. https://bugzilla.gnome.org/show_bug.cgi?id=694771
