OvmfPkg: QemuBootOrderLib: OFW-to-UEFI translation for virtio-mmio

Browse Source 
The TranslateMmioOfwNodes() function recognizes the following OpenFirmware
device paths:

  virtio-blk:       /virtio-mmio@000000000a003c00/disk@0,0
  virtio-scsi disk: /virtio-mmio@000000000a003a00/channel@0/disk@2,3
  virtio-net NIC:   /virtio-mmio@000000000a003e00/ethernet-phy@0

The new translation can be enabled with the
"PcdQemuBootOrderMmioTranslation" Feature PCD. This PCD also controls if
the "survival policy" covers unselected boot options that start with the
virtio-mmio VenHw() node.
