arch/sim: add SIM_RPMSG_VIRTIO Kconfig option

Add a new Kconfig option SIM_RPMSG_VIRTIO to enable RPMsg VirtIO Lite
driver support for the simulator. This option automatically selects
RPMSG_VIRTIO_LITE when enabled.

Also update rpproxy_virtio and rpserver_virtio defconfigs to enable
this new option.
