target/s390x: filter deprecated properties based on model expansion type

Browse source 
Currently, there is no way to execute the query-cpu-model-expansion
command to retrieve a comprehenisve list of deprecated properties, as
the result is dependent per-model. To enable this, the expansion output
is modified as such:

When reporting a "full" CPU model, show the *entire* list of deprecated
properties regardless if they are supported on the model. A full
expansion outputs all known CPU model properties anyway, so it makes
sense to report all deprecated properties here too.

This allows management apps to query a single model (e.g. host) to
acquire the full list of deprecated properties.

Additionally, when reporting a "static" CPU model, the command will
only show deprecated properties that are a subset of the model's
*enabled* properties. This is more accurate than how the query was
handled before, which blindly reported deprecated properties that
were never otherwise introduced for certain models.
