vmm: Convert virtio devices to Arc<Mutex<T>>
Migratable devices can be virtio or legacy devices. In any case, they can potentially be tracked through one of the IO bus as an Arc<Mutex<dyn BusDevice>>. In order for the DeviceManager to also keep track of such devices as Migratable trait objects, they must be shared as mutable atomic references, i.e. Arc<Mutex<T>>. That forces all Migratable objects to be tracked as Arc<Mutex<dyn Migratable>>. Virtio devices are typically migratable, and thus for them to be referenced by the DeviceManager, they now should be built as Arc<Mutex<VirtioDevice>>.
