[9.x] Allow factories to recycle models with for method

[jessarcher]

This PR addresses #44107 (comment) where using the Factory for method instead of specifying a 'model_id' => Model::factory() definition does not use recycled models. I think this makes sense, although typically you'd call for from your test where you could just pass the model directly, so I think it's more of an edge case.

I considered adding support for the has method as well, however, I don't think that one makes as much sense. If the recycled model belongs to another model, then I don't think it's parent relationship should be re-assigned, especially if it's part of a has many relationship where more than one model might be needed. I could make it attach the model in a many-to-many relationship, but it would probably need to be conditional on whether one or many models were requested. In any case, I can't think of a scenario where this would be a papercut so I'm not inclined to look into it further right now.

I wasn't too keen on making the recycle property public as it doesn't match the other properties. But I thought it might also be overkill to create a public method to access it.
