REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2841
Currently, we have TCG/TCG2 protocol and DxeTpmMeasurementLib to let DXE module extend the TCG event. There is more and more use case in PEI phase that a PEIM need extend TCG event, such as BootGuard, FSP, Microcode measurement. Currently, we dont have API to do that so that each module need create TCG/TCG2 event log, which is a burden. This bugzilla requests to add PeiTpmMeasurementLib instance. The implementation includes: 1) A EDKII_TCG_PPI which abstracts the HashLogExtendEvent service. 2) A PeiTpmMeasurementLib instance, so that a PEIM can call this API to add TCG event.
