Retain a list of deprecated features disjoint from any particular

properties (i.e. features) that are flagged as deprecated. Example:

"return": {

"name": "z14.2-base",
"deprecated-props": [
"bpb",
"csske"
],
"props": {
"pfmfi": false,
"exrl": true,
...a lot more props...
"skey": false,
"vxpdeh2": false

It is recommended that s390 guests operate with these features
explicitly disabled to ensure compatability with future hardware.
Likely you should only report features that are applicable to a model.
that is, if it's part of the full_feat.
Otherwise, the caller might simply want do set all features to "false",
and we'd fail setting a feature that is unknown to a specific CPU
generation.
That is, you would AND the bitmap with the full_feat of the underlying
CPU definition.
