OvmfPkg: Refactor MeaureFvImage
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4243
MeasureFvImage once was implemented in PeilessStartupLib and it does
measurement and logging for Configuration FV (Cfv) image in one go,
using TpmMeasureAndLogData(). But it doesn't work in SEC.
This patch splits MeasureFvImage into 2 functions and implement them in
SecTdxHelperLib.
- TdxHelperMeasureCfvImage
- TdxHelperBuildGuidHobForTdxMeasurement
TdxHelperMeasureCfvImage measures the Cfv image 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 MeasureFvImage
- Delete the duplicated codes in PeilessStartupLib
