OvmfPkg: introduce VIRTIO_MMIO_TRANSPORT_GUID

Soon there will be more than one modules (in separate packages) that need
to have an understanding about the GUID used in the VenHw() device path
nodes that describe virtio-mmio transports. Define such a GUID explicitly.

Preserve the current value (which happens to be the FILE_GUID of
ArmPlatformPkg/ArmVirtualizationPkg/VirtFdtDxe/VirtFdtDxe.inf) for
compatibility with external users.
