-----------
ArmVirtualizationPkg: VirtFdtDxe: use dedicated VIRTIO_MMIO_TRANSPORT_GUID
Installing VenHw() device paths with this GUID, for the virtio-mmio
transports that we detect, enables other modules to recognize those
VenHw() nodes. (Note that the actual value doesn't change.)
In addition, to avoid reusing GUIDs in unrelated contexts, detach the
driver's FILE_GUID from its previous value.
