ui/console: fire console ADDED/REMOVED notifications
Fire CONSOLE_ADDED at the end of graphic_console_init() and CONSOLE_REMOVED at the start of graphic_console_close(), so display backends can react to console hotplug/unplug events. REMOVED fires before the device link is cleared and before the placeholder surface swap, so handlers can unregister their DCL while the console is still in a known state.
