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.

OvmfPkg: Add AMD SEV-ES DebugVirtualization feature support
The SEV-ES DebugVirtualization feature enables type B swapping of
debug registers on #VMEXIT and makes #DB and DR7 intercepts
unnecessary and unwanted.
When DebugVirtualization is enabled, this stops booting if
interaction from the HV.
Add new API to PEI, SEC, DXE.
This does not change the existing behaviour yet.

UefiCpuPkg: Add AMD SEV-ES features support
CONFIDENTIAL_COMPUTING_GUEST_ATTR is not a simple SEV level anymore
and includes a feature mask since the previous commit.
Fix AmdMemEncryptionAttrCheck to check the level and feature
correctly and add DebugVirtualization support.
Since the actual feature flag is not set yet, this should cause
no behavioural change.
