Don't inherit from both interfaces if one interface inherits from another

[nettrino]

Given the GraphQL

  interface ResourceEntity {
  ...
  }

  interface CloudResourceEntity implements ResourceEntity {
  ...

  }

   type AWSCloudPlatform implements CloudPlatform & CloudResourceEntity & ResourceEntity {
   ...
  }

@dataclass(kw_only=True)
class AWSCloudPlatform(CloudPlatform, ResourceEntity, CloudResourceEntity):
  ...

whereas the right code to be emitted is

@dataclass(kw_only=True)
class AWSCloudPlatform(CloudPlatform, CloudResourceEntity):
  ...
