Please describe the feature.

After #51067 we will need to update the generator to automatically add ModelReaderWriterBuildableAttributes for all IPersistableModels and any properties of those models that are also IPersistableModels

There should be 1 attribute for each model that implements IPersistableModel as well as 1 for every property of that model recursively removing duplicates.
