test(generator): 添加批量注册集合生成器的单元测试

- 添加了针对注解集合生成批处理注册方法的测试用例
- 添加了当集合元素类型无法推断时报告诊断的测试
- 添加了注册方法使用数组参数时的批处理注册测试
- 添加了从继承接口获取注册方法的批处理注册测试
- 添加了从基类获取注册方法的批处理注册测试
- 添加了当集合成员不可实例读取时报告诊断的测试
- 添加了当注册成员不可实例读取时报告诊断的测试
- 添加了当注册方法对所有者类型不可访问时报告诊断的测试
- 添加了当注册导出集合属性参数无效时报告诊断的测试
- 添加了多个分部声明注解时仅生成一个源文件的测试
- 为枚举候选方法功能添加了详细的XML文档注释
