refactor(form): 抽出 TableGroupList 父组件统一管理 Table/GroupList 切换

- 新增 TableGroupList 父组件集中持有 displayMode 状态并派生两种形态的
  config，避免原实现通过直接改写 props.config 来触发视图切换
- 将公共的 toggle/add 按钮上移到 TableGroupList，Table/GroupList 通过
  具名 slot + scoped slot 暴露位置与业务钩子（newHandler/addHandler）
- m-form-table、m-form-group-list 统一注册为 TableGroupList，对外导出
  的 MTable/MGroupList 也指向它，新增 MTableGroupList 显式导出
- useAdd 移除重复的 addable 计算，由父组件统一管理
