根据项目要求，需要在setting中添加一项专门管理直播设置的内容，添加步骤如下（参考displaysetting 进行添加）：
1. 添加liveSetting到SettingsHomepageActivity

参考displaysetting，将电池相关的setting更改为livesetting，提供livesetting的fragment：com.android.settings.LiveSettings ，controller：com.android.settings.klive.TopLevelLivePreferenceController
2. 参考displaysetting 新建LiveSettings 、TopLevelLivePreferenceController和R.xml.live_settings

此xml即为livesetting的布局文件，目前只添加了虚拟摄像头开关这一个选项，后续需要增加可以参考添加
3. 虚拟摄像头controller 添加
要实现虚拟摄像头开关 相关逻辑需要添加到controller当中
