What to do: 1. Move TpmMeasurementLib LibraryClass from SecurityPkg to MdeModulePkg. 2. Implement a NULL TpmMeasurementLib library instance. Why to do: 1. Share code. We are moving forward to separate auth variable service from Auth Variable driver in SecurityPkg to AuthVariableLib. Then the AuthVariableLib could benefit and be used by different implementation of Auth Variable drivers. 2. Remove code duplication and reduce maintenance effort. After auth variable service separated from Auth Variable driver in SecurityPkg to AuthVariableLib. The remaining code logic of Auth Variable driver in SecurityPkg will be almost same with Variable driver in MdeModulePkg. We are going to merge them. 3. TpmMeasurementLib is consumed by Auth Variable driver in SecurityPkg now, as Auth Variable driver in SecurityPkg will be merged to Variable driver in MdeModulePkg, so the library class also needs to be moved to MdeModulePkg.
