OvmfPkg/HardwareInfoLib: add support for qemu vars device
Add SIMPLE_INFO for devices which only have an mmio address.
Add HardwareInfoTypeQemuUefiVars type.
While being at it remove HardwareInfoTypeMax. Looks pointless
to have it, we never loop over the available types.

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.

OvmfPkg: add PcdQemuVarsRequire
Add PcdQemuVarsRequire FeaturePcd, so firmware code can figure whenever
the given build is supposed to use the qemu uefi variable service.
Skip the emulated variable store setup in case PcdQemuVarsRequire is
true. This is needed to make secure boot work.
