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 - 5:
  Introduce TdxHelperLib which provides helper functions for td-guest.

Patch #6/7:
  These 2 patches are the changes for OvmfPkg/IntelTdx because of the
  introduction of TdxHelperLib.

Patch #8/9:
  These 2 patches are the changes for OvmfPkg/OvmfPkgX64 to enable Tdx
  measurement.

Patch #10:
  ProcessTdxHobList is moved to TdxHelperLib and is renamed as
  TdxHelperProcessTdHob(). So the duplicated codes are deleted in this
  patch.

Code: https://github.com/mxu9/edk2/tree/TdxMeasurementInOvmfX64.v2

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.
