Macbook Pro 用外接显示器时，如何关闭笔记本屏幕，同时开盖使用？

CGGetActiveDisplayList
CGDisplayIsBuiltin
CGBeginDisplayConfiguration
CGSConfigureDisplayEnabled
CGSCompleteDisplayConfiguration

完成一个 python 脚本，功能：
1. 如果系统不是 macos，报错退出
2. 如果处理器不是 apple silicon，报错退出
3. 获取显示器列表，如果仅包含内建显示器，无连接的外部显示器，则强制开启内建显示器
4. 如果同时包含内建显示器和外部显示器，则 toggle 内建显示器的开关状态，进行 toggle 前要通过交互提示用户是否确认；



以下为可能用到的公有和私有 API：
CGGetActiveDisplayList
CGDisplayIsBuiltin
CGBeginDisplayConfiguration
CGSConfigureDisplayEnabled
CGSCompleteDisplayConfiguration
