Mac Catalyst

FFmpegKitNext build scripts support building Mac Catalyst architectures. However, the older iOS framework format cannot store Mac Catalyst and non-Mac Catalyst architectures in the same bundle. Therefore, the --xcframework option must be provided to build FFmpegKitNext with Mac Catalyst support. The --xcframework option builds FFmpegKitNext as an xcframework bundle, where both architecture types can coexist.
