GUID gEdkiiCpuFeaturesSetDoneGuid is used to indicate if CPU feature related
setting are set finished. For example, PCD PcdCpuFeaturesUserConfiguration.

On PEI phase, one gEdkiiCpuFeaturesSetDoneGuid PPI will be installed after
platform set CPU feature setting.
On DXE phase, one gEdkiiCpuFeaturesSetDoneGuid Protocol will be installed after
platform set CPU feature setting.
