SecurityPkg: Add new gEdkiiTcg2AcpiCommunicateBufferHobGuid
Add a new GUID HOB gEdkiiTcg2AcpiCommunicateBufferHobGuid.
This Tcg2 Acpi Communicate Buffer HOB is used to store the
address of a buffer reserved for Tcg2Acpi driver. The buffer
will be used to retrive information from Standalone mm
environment.
