[PATCH ovmf 2/5] MdePkg: Add AMD SEV features to PcdConfidentialComputingGuestAttr

["Alexey Kardashevskiy" <aik@amd.com>]

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

This adds the features mask and the DebugSwap feature bit to a PCD.
