SecurityPkg: Support CcMeasurementProtocol in DxeTpm2MeasureBootLib

Browse Source 
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3625

DxeTpm2MeasureBootLib supports TPM2 based measure boot. After
CcMeasurementProtocol is introduced, CC based measure boot needs to
be supported in DxeTpm2MeasureBootLib as well.

There are 2 major changes in this commit.

1. A platform should have only one RTS/RTR. Only one of (virtual)TPM1.2,
(virtual)TPM2.0 and CC MR exists. Then only one TCG_SERVICE_PROTOCOL,
TCG2_PROTOCOL, CC_MEASUREMENT_PROTOCOL is exposed. In this library when
do measure boot only one of TCG2_PROTOCOL / CC_MEASUREMENT_PROTOCOL
will be called. MEASURE_BOOT_PROTOCOLS is defined to store the instances
of TCG2 protocol and CC Measurement protocol.

2. CcEvent is similar to Tcg2Event except the MrIndex and PcrIndex.
So in the code Tcg2Event will be first created and intialized. If
CcMeasurementProtocol is called to do the measure boot, then CcEvent
points to Tcg2Event and the MrIndex is adjusted.
