Jason Macnak 1e077db461 devices: gpu: Support display hotplug ... Adds `crosvm gpu <>` commands which allows for interactively adding/listing/removing virtio-gpu displays/scanouts. Also updates the virtio gpu device to use a Map<u32, Scanout> instead of a Vec<Scanout> and always report the maximum number of displays (16) with enabled/disabled. This helps handle the case of removing a display that is not the last display number.
