qapi/qom: Add ObjectOptions for confidential-guest-support

This adds a QAPI schema for the properties of the objects implementing
the confidential-guest-support interface.

pef-guest and s390x-pv-guest don't have any properties, so they only
need to be added to the ObjectType enum without adding a new branch to
ObjectOptions.
