qxl: add a connector property to denote hotplug should rescan modes.
So GNOME userspace has an issue with when it rescans for modes on hotplug events, if the monitor has no EDID it assumes that nothing has changed on EDID as with real hw we'd never have new modes without a new EDID, and they kind off rely on the behaviour now, however with virtual GPUs we would like to rescan the modes and get a new preferred mode on hotplug events to handle dynamic guest resizing (where you resize the host window and the guest resizes with it). This is a simple property we can make userspace watch for to trigger new behaviour based on it, and can be used to replaced EDID hacks in virtual drivers.
