David Gibson f91f9f254b confidential guest support: Introduce new confidential guest support class
Several architectures have mechanisms which are designed to protect
guest memory from interference or eavesdropping by a compromised
hypervisor.  AMD SEV does this with in-chip memory encryption and
Intel's TDX can do similar things.  POWER's Protected Execution
Framework (PEF) accomplishes a similar goal using an ultravisor and
new memory protection features, instead of encryption.

To (partially) unify handling for these, this introduces a new
ConfidentialGuestSupport QOM base class.  "Confidential" is kind of vague,
but "confidential computing" seems to be the buzzword about these schemes,
and "secure" or "protected" are often used in connection to unrelated
things (such as hypervisor-from-guest or guest-from-guest security).

The "support" in the name is significant because in at least some of the
cases it requires the guest to take specific actions in order to protect
itself from hypervisor eavesdropping.
