Min M Xu efaf8931bb OvmfPkg/TdTcg2Dxe: Fix the SeparatorEvent issue in RTMRs 
According to the TCG EFI platform specification, the firmware must
measure the EV_SEPARATOR event into PCRs 0-7. As PCR[1] and PCR[7]
map to RTMR[0], and PCRs [2-6] map to RTMR[1], it is necessary to
measure one EV_SEPARATOR event into RTMR[0] and another one into
RTMR[1].

An issue is found in TdTcg2Dxe that 2 EV_SEPARATOR events are measured
to RTMR[0] but no EV_SEPARATOR event is measured to RTMR[1]. This
patch fixes the above issue.
