Marc-André Lureau 285689a3f1 ui: add display cleanup infrastructure ...

Add a cleanup callback to QemuDisplay and a qemu_display_cleanup()
function that iterates all registered display types and calls their
cleanup handler. Wire it into qemu_cleanup() in runstate.c, replacing
the ad-hoc vnc_cleanup() call.

This provides a structured alternative to atexit() handlers, giving
deterministic teardown ordering and making resource leaks visible to
sanitizers.

The cleanup should happen before user_creatable_cleanup(), since some
display have weak user-creatable references to cleanup before.
