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.
