Fix #695 - support recursive intersection type

[samchon]

typia could not validate recursive intersection type like below.

Of course, below type is an extremely crazy case, but as goal of typia is to supporting every TypeScript types, I've fixed it.

export type ISetupConfig =
  | ({
      type: 'Main';
    } & ISetupConfigMain)
  | ({
      type: 'Before';
    } & ISetupConfigBefore)
  | ({
      type: 'After';
    } & ISetupConfigAfter);

export type ISetupConfigMain = {
  content: ISetupConfig;
};

export type ISetupConfigBefore = {
  content: ISetupConfig;
};

export type ISetupConfigAfter = {
  content: ISetupConfig;
};

OK, no problem.
