This adds an x-is-free-form vendor extension to allow users to skip our "free-form" logic which would previously prevent object schemas with no properties to be considered "free-form". The previous behavior was due in part to Swagger Parser not exposing `additionalProperties: false` to us (which should be similar behavior to this extension). A free-form object is considered a dynamic object with any number of properties/types. DefaultGenerator does not allow for generation of models considered free-form. However, a base type with no properties and no additional properties is allowed by OpenAPI Specification and is meaningful in many languages (e.g. "marker interfaces" or abstract closed types).
