MdePkg/Svsm: add SVSM_UEFI_MM_PROTOCOL
The SVSM_UEFI_MM_PROTOCOL protocol allows to send MM communication buffers to
the SVSM (instead of edk2 MM code) and let SVSM manage EFI variables that way.
This patch adds protocol and call numbers to svsm include file.

UefiCpuPkg/AmdSvsmLib: add AmdSvsmUefiMmRequest
The SVSM_UEFI_MM_PROTOCOL protocol allows to send MM communication buffers to
the SVSM (instead of edk2 MM code) and let SVSM manage EFI variables that way.
This patch adds a helper function to send MM communication buffers to the SVSM
to the AmdSvsmLib library header and a stub function to the Null library
implementation.

OvmfPkg/AmdSvsmLib: add AmdSvsmUefiMmRequest
The SVSM_UEFI_MM_PROTOCOL protocol allows to send MM communication buffers to

This patch implements the helper function to send MM communication buffers to
the SVSM for the OVMF AmdSvsmLib implementation.

OvmfPkg/VirtMmCommunicationDxe: add SVSM support
When running on SVSM check whenever SVSM_UEFI_MM_PROTOCOL is supported, and if
that is the case send MM communication requests to the SVSM (instead of the
qemu uefi-vars device).
