dev: Add a dummy VirtIO device
VirtIO transport interfaces always expect a VirtIO device pointer. However, there are cases (in particular when using VirtIO's MMIO interface) where we want to instantiate an interface without a device. Add a dummy device using VirtIO device ID 0 and no queues to handle this use case.
