Currently, virQEMUCapsUpdateCPUDeprecatedFeatures only allows for
disabling deprecated features. This locks the deprecated_features
attribute to only do something if set to 'off'.
Let's add a virCPUFeaturePolicy to the function's parameters which will
allow the caller to decide what happens to these features.
Add a test with guest XML using deprecated_features='on' to ensure the
API is working properly.
