CC_MR_INDEX_0_MRTD indicates the MRTD register. This register is NOT
extendable in TDVF. So the return value of TdxMeasurementMapPcrToMrIndex
must be checked.

TDVF has the feature to do RTMR measurement in SEC phase. In the same time
it builds a GUID hob which carries the hash value of the measurement so
that in DXE phase a td event can be created based on this GUID Hob. There
is a mapping error between TPM PCR index and RTMR index according to UEFI
2.10. That PCR6 is missing in the mapping. This patch fixes this issue.

SecTpmMeasurementLitTdx is an instance of TpmMeasurementLib. It is
designed to used in a Td guest. This lib measures and logs data, and
extendx the measurement result into a specific RTMR.
SecTpmMeasurementLibTdx is a refactored lib of
OvmfPkg/Library/SecMeasurementLibTdx and it just copies
GetMappedRtmrIndex/TdxMeasureAndLogData from that lib. At the end of
this patch-set SecMeasurementLibTdx will be deleted.
