OvmfPkg/VirtioPciDeviceDxe: implement IOMMU-like member functions
The patch implements the newly added IOMMU-like member functions by
respectively delegating the job to:
- VIRTIO_DEVICE_PROTOCOL.AllocateSharedPages () ->
MemoryAllocationLib.AllocatePages()
- VIRTIO_DEVICE_PROTOCOL.FreeSharedPages () ->
MemoryAllocationLib.FreePages ()
- VIRTIO_DEVICE_PROTOCOL.MapSharedBuffer () -> no-op
- VIRTIO_DEVICE_PROTOCOL.UnmapSharedBuffer () -> no-op
