Min Xu f8264e1303 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.

Min Xu d5efc875ef MdePkg: Introduce CcMeasurementProtocol for CC Guest firmware
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3625

CC guest is a Confidential Computing guest. If CC Guest firmware
supports measurement and an event is created, CC Guest firmware
is designed to report the event log with the same data structure
in TCG-Platform-Firmware-Profile specification with
EFI_TCG2_EVENT_LOG_FORMAT_TCG_2 format.

The CC Guest firmware supports measurement. It is designed to
produce EFI_CC_MEASUREMENT_PROTOCOL with new GUID
EFI_CC_MEASUREMENT_PROTOCOL_GUID to report event log and provides
hash capability.
