OvmfPkg: add new VirtMmCommunicationDxe driver
EFI driver implementing the MmCommunication2Protocol,
but instead of trapping to MM mode (SMM on x86, el3 on arm)
trap to the host, using a virtual device.
Moving the efi variable management to the host allows to have
persistent efi variables without flash storage, and it also
allows to have secure boot support without requiring MM mode
to protect variable storage in flash.
On x86 etc/hardware-info is used for device discovery, on arm
the FDT will be consulted.
