OvmfPkg/VirtioGpuDxe: negotiate VIRTIO_F_IOMMU_PLATFORM
VirtioGpuDxe is now IOMMU-clean; it translates system memory addresses to
bus master device addresses. Negotiate VIRTIO_F_IOMMU_PLATFORM in parallel
with VIRTIO_F_VERSION_1. (Note: the VirtIo GPU device, and this driver,
are virtio-1.0 only (a.k.a. "modern-only").)
