OvmfPkg/TdTcg2Dxe: Fix the mapping error between PCR index and MR index
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4179
According to UEFI Spec 2.10 it is supposed to return the mapping from PCR
index to CC MR index:
//
// In the current version, we use the below mapping for TDX:
//
// TPM PCR Index | CC Measurement Register Index | TDX-measurement register
// -----------------------------------------------------------------------
// 0 | 0 | MRTD
// 1, 7 | 1 | RTMR[0]
// 2~6 | 2 | RTMR[1]
// 8~15 | 3 | RTMR[2]
In the current implementation TdMapPcrToMrIndex returns the index of RTMR,
not the MR index.
After fix the spec unconsistent, other related codes are updated
accordingly.
1) The index of event log uses the input MrIndex.
2) MrIndex is decreated by 1 before it is sent for RTMR extending.

OvmfPkg/SecTpmMeasurementLib: Fix the mapping error of PCR and RTMR index
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4179
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.
