OvmfPkg: Refactor MeasureHobList
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4243
MeasureHobList once was implemented in PeilessStartupLib and it does
measurement and logging for TdHob in one go, using TpmMeasureAndLogData().
But it doesn't work in SEC.
This patch splits MeasureHobList into 2 functions and implement them in
SecTdxHelperLib.
- TdxHelperMeasureTdHob
- TdxHelperBuildGuidHobForTdxMeasurement
TdxHelperMeasureTdHob measures the TdHob and stores the hash value in
WorkArea. TdxHelperBuildGuidHobForTdxMeasurement builds GuidHob for the
measurement based on the hash value in WorkArea.
After these 2 functions are introduced, PeilessStartupLib should also be
updated:
- Call these 2 functions instead of the MeasureHobList
- Delete the duplicated codes in PeilessStartupLib
