MdePkg: Define CC Measure EventLog ACPI Table
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3853
TDVF set up an ACPI table (EFI_CC_EVENTLOG_ACPI_TABLE) to pass the
event-log information. The event log created by the TD owner contains
the hashes to reconstruct the MRTD and RTMR registers.
Please refer to Sec 4.3.3 in blow link:
https://www.intel.com/content/dam/develop/external/us/en/documents/
intel-tdx-guest-hypervisor-communication-interface-1.0-344426-002.pdf
Please be noted, the definition of EFI_CC_EVENTLOG_ACPI_TABLE is a
little different from the above document. This difference is based on
below discussion:
- https://edk2.groups.io/g/devel/message/87396
- https://edk2.groups.io/g/devel/message/87402
This change will be reflected in the next version of the above document.
