OvmfPkg: Introduce SecMeasurementLib
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3853
SecMeasurementLib is designed to do the measurement in SEC phase. In
current stage there are 2 functions introduced:
- MeasureHobList: Measure the Hoblist passed from the VMM.
- MeasureFvImage: Measure the FV image.
SecMeasurementLibTdx is the TDX version of the library.
