SecurityPkg: Support CcMeasurementProtocol in DxeTpmMeasurementLib

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

DxeTpmMeasurementLib supports TPM based measurement in DXE phase.
After CcMeasurementProtocol is introduced, CC based measurement needs
to be supported in DxeTpmMeasurementLib as well.

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 measurement only one of above 3 protocols will
be called.
