SecurityPkg: Add definition of EFI_CC_EVENT_HOB_GUID
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3853
EFI_CC_EVENT_HOB_GUID is the global ID of a GUIDed HOB used to pass
TDX_DIGEST_VALUE from SEC to a DXE Driver ( This DXE driver will
be introduced in the following commit in this patch-sets ). In that
DXE driver this GUIDed HOB will be parsed and the TDX_DIGEST_VALUE
then will be extracted. After that a EFI_CC_EVENT will be created
based on it.
