remote/machine: add vfio-user property
Add vfio-user to x-remote machine. It is a boolean, which indicates if
the machine supports vfio-user protocol. The machine configures the bus
differently vfio-user and multiprocess protocols, so this property
informs it on how to configure the bus.
This property should be short lived. Once vfio-user fully replaces
multiprocess, this property could be removed.
