[PATCH V4 00/12] Enable Tdx measurement in OvmfPkgX64

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4243

Tdx measurement (RTMR based measurement) is enabled in OvmfPkg/IntelTdx.
This patch-set enables the feature in OvmfPkgX64 as well.

Patch #1:
Introduce TDX_MEASUREMETNS_DATA in SEC_TDX_WORK_AREA. That is because
the RTMR measurement of TdHob and Configuration FV (CFV) are executed
in very early stage of boot process. At that time the memory service is
not ready and the measurement values have to be stored in OvmfWorkArea.

Patch #2:
Introduce TdxHelperLibNull which is the NULL instance of TdxHelperLib.

Patch #3:
Introduce SecTdxHelperLib which is the instance of TdxHelperLib for SEC
Phase. In this patch TdxHelperBuildGuidHobForTdxMeasurement and
TdxHelperProcessTdHob are not implemented. Their implementation are in
patch #9 and patch #5. This is for the patch to be reviewed more
friendly.

Patch #4:
SecMain.c in IntelTdx is updated with the new functions provided
by TdxHelperLib.

Patch #5-8:
To make the code reviewable, the implementation of
TdxHelperBuildGuidHobForTdxMeasurement is split into 4 patches (5-8).

Patch #10:
This patch introduce PeiTdxHelperLib which is for PEI phase.

Patch #9/11:
These 2 patches are the changes for OvmfPkg/OvmfPkgX64 to enable Tdx
measurement.

Patch #12:
This patch implements TdxHelperProcessTdHob which is moved from
PlatformInitLib/IntelTdx.c. Its counterpart in PlatformInitLib is
ProcessTdxHobList and the duplicated codes are deleted in this patch.

Code: https://github.com/mxu9/edk2/tree/TdxMeasurementInOvmfX64.v4

v4 changes:
- To make the code reviewable, the implementation of
TdxHelperBuildGuidHobForTdxMeasurement is split into 4 patches (5-8).
- Call Sha384HashAll instead of the 3 Sha384XXX functions so that we
need to allocate memory in SEC phase.

v3 changes:
- Use the definition of PLATFORM_FIRMWARE_BLOB2_STRUCT in
Library/TcgEventLogRecordLib.h.
- Rename TDX_ENABLE as TDX_MEASUREMENT_ENABLE because this flag is
introduced for Tdx-measurement.
- Split the patch of SecTdxHelperLib into 2 separate patches (#3/#9).
Patch#3 implements TdxHelperMeasureTdHob and TdxHelperMeasureCfvImage.
Patch#9 implements TdxHelperProcessTdHob. This is to make the patches
more reviewable. The duplicated codes of TdxHelperProcessTdHob are
deleted in Patch#9 as well.
- The implementation of TdxHelperBuildGuidHobForTdxMeasurement and update
of PeilessStartupLib are in one patch (#5). Because the implmentation
of TdxHelperBuildGuidHobForTdxMeasurement was once in PeilessStartupLib.

v2 changes:
- Split the patch of TdxHelperLib into 4 separate patches. So that it is
more reviewable.
- Add commit message in Patch#1 to emphasize that the tdx-measurement in
OvmfPkgX64 is supported in SEC phase.
