BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4243 TdxHelperLib provides below helper functions for a td-guest. - TdxHelperProcessTdHob - TdxHelperMeasureTdHob - TdxHelperMeasureCfvImage - TdxHelperBuildGuidHobForTdxMeasurement SecTdxHelperLib is the SEC instance of TdxHelperLib. It implements 4 functions for tdx in SEC phase: - TdxHelperProcessTdHob consumes TdHob to accept un-accepted memories. Before the TdHob is consumed, it is first validated. - TdxHelperMeasureTdHob measure/extend TdHob and store the measurement value in workarea. - TdxHelperMeasureCfvImage measure/extend the Configuration FV image and store the measurement value in workarea. - TdxHelperBuildGuidHobForTdxMeasurement builds GuidHob for tdx measurement. This patch implements the stubs of the functions. The actual implementations are in the following patches. Because they are moved from other files.
