MdePkg: Add AMD SEV features to PcdConfidentialComputingGuestAttr 

PcdConfidentialComputingGuestAttr so far only contained an SEV mode bit
but there are more other features which do not translate to levels
such as DebugVirtualization or SecureTsc.

Add the feature mask and the DebugVirtualization feature bit to the PCD.
