feat(MultipleTab): add tabs auto collapse interaction and setting

[xachary]

General

部分页面在开启“fold”模式下，希望达到“沉浸式”的全屏展示，同时不影响“tabs”的切换，且相比于“fullContent”模式需要点击2次才能切换，增加“fold”模式下“tabs”可以自动收起，可以1次点击即可切换。

我这边还有一个调整，上述的模式下，“fold”的时候"设置"按钮会移动到“tabs”栏上面（“刷新”按钮左边），先看看这个模式是否通过你们的评审。

@xachary 我开启了 自动收起标签页 标签切换好像没有变化, 能否详细描述下或者录制个视频 这个功能该如何使用吗？

[xachary]

@wangjue666 好的，请看：

”fold“的时候才会生效获得”全屏“的体验

在这个前提下，还可以优化浮动的设置按钮显示逻辑，可以”fold“的时候可以显示在标签栏上（我项目中是这样优化的）。

@xachary 可以，你可以重新fork下仓库，开个新分支进行pr，这样你之前提交的commit信息不会出现在新pr里面

每次pr前主动点下更新这样可以尽可能避免代码冲突
