OvmfPkg/Microvm/fdt: load fdt from fw_cfg
Needed for hardware detection: virtio-mmio devices for now,
later also pcie root bridge.
Depends on patched qemu which actually provides an fdt:

OvmfPkg/Microvm/fdt: add empty fdt
FdtClient is unhappy without a device tree, so add an empty fdt
which we can use in case etc/fdt is not present in fw_cfg.
On ARM machines a device tree is mandatory for hardware detection,
that's why FdtClient fails hard.
On microvm the device tree is only used to detect virtio-mmio devices
(this patch series) and the pcie host (future series). So edk2 can
continue with limited functionality in case no device tree is present:
no storage, no network, but serial console and direct kernel boot
works.
qemu release 6.2 & newer will provide a device tree for microvm.

OvmfPkg/Microvm/virtio: add virtio-mmio support
Add virtio-mmio support (VirtioMmioDeviceLib and VirtioFdtDxe).
With this patch added and a new enough qemu version (6.2+) edk2
will detect virtio-mmio devices, so it is possible to boot from
storage (virtio-blk, virtio-scsi) or network (virtio-net).
