OvmfPkg/IntelTdx: Measure Td HobList and Configuration FV

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3853

TdHobList and Configuration FV are external data provided by Host VMM.
These are not trusted in Td guest. So they should be validated , measured
and extended to Td RTMR registers. In the meantime 2 EFI_CC_EVENT_HOB are
created. These 2 GUIDed HOBs carry the hash value of TdHobList and
Configuration FV. In DXE phase EFI_CC_EVENT can be created based on these
2 GUIDed HOBs.
