[新增目标色彩空间设置功能]：在播放器中增加了目标色彩空间的设置选项，允许用户根据需要选择不同的色彩空间。

RealChuan · RealChuan · commit 5a01e1b602f2 · 2024-06-17T13:24:52.000+08:00
- 在`ffmpegplayer`和`mpvplayer`的`mainwindow`中新增了`createTargetPrimariesMenu`函数，用于创建目标色彩空间的菜单选项。
- 为`ffmpegplayer`的`MainWindow`类新增了连接，当用户选择不同的目标色彩空间时，会更新视频渲染器的色彩空间设置。
- 为`mpvplayer`的`MpvPlayer`类新增了获取、设置目标色彩空间的函数，并在`mpvplayer`的`MainWindow`中使用了这些新函数来响应用户的选择。
- 移除了`ffmpegplayer`中旧的`destPrimarisMenu`函数，并用新的功能替换。
- 更新了`mpvplayer`的`MpvPlayer`类头文件，添加了目标色彩空间相关的公共成员函数声明。
