每次子表更新时都会全部删除再重建 逻辑上没问题，但子表使用逻辑删除时，数据库中会产生很多重复的脏数据 于是参考`cn.iocoder.yudao.module.system.service.permission.PermissionServiceImpl#assignRoleMenu`方法，封装了一个通用的子表批量更新方法 处理逻辑如下： 1. 带id的数据 => 需要修改 2. 没有id的数据 => 需要添加 3. 数据库里有这个id，但前端传过来的数据没有 => 需要删除
注：使用 == null 判断而不是 isEmpty，是因为可能有些场景下，需要清空子表

顺便把该方法加到代码模板里了
