Use minimal prebuilt FFmpeg for Windows

On the scrcpy-deps repo, I built FFmpeg 5.1.2 binaries for Windows with only the features used by scrcpy. For comparison, here are the sizes of the dll for FFmpeg 5.1.2: - before: 89M - after: 4.7M It also allows to upgrade the old FFmpeg version (4.3.1) used for win32.
