PcdConfidentialComputingGuestAttr can be used to check the cc guest type, including td-guest or sev-guest. CcProbe() can do the same thing but CcProbeLib should be included in the dsc which uses AcpiPlatformDxe. The difference between PcdConfidentialComputingGuestAttr and CcProbe() is that PcdConfidentialComputingGuestAttr cannot be used in multi-processor scenario but CcProbe() can. But there is no such issue in AcpiPlatformDxe. So we use PcdConfidentialComputingGuestAttr instead of CcProbeLib so that it is simpler.
