OvmfPkg/Virtio10Dxe: 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() ->
    EFI_PCI_IO_PROTOCOL.AllocateBuffer()

- VIRTIO_DEVICE_PROTOCOL.FreeSharedPages() ->
    EFI_PCI_IO_PROTOCOL.FreeBuffer()

- VIRTIO_DEVICE_PROTOCOL.MapSharedBuffer() ->
    EFI_PCI_IO_PROTOCOL.Map()

- VIRTIO_DEVICE_PROTOCOL.UnmapSharedBuffer() ->
    EFI_PCI_IO_PROTOCOL.Unmap()
