* FFmpeg: update layout api for ffmpeg 6.x and ffmpeg 7.

After ffmpeg 5.1, it is deprecated, and has been completely removed in ffmpeg 7.

Our current project is using 6.0 headers, modifying it will not have any side effects.

Since lavu 57.24.100(ffmpeg 5.1)

* FFmpeg: dynamic_library and dumping adapt to ffmpeg7.1.

But keeping support for older versions.

* externals/library-headers: update ffmpeg to 7.1
