[PATCH 5/8] MdePkg: Define CC Measure EventLog ACPI Table

["Min Xu" <min.m.xu@intel.com>]

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:
