Fixed loading Video files with no extension on Mac

[3llomi]

Currently AVURLAsset doesn't recognize the video file if it doesn't have an extension e.g. '.mp4'
So I added a mime type detection so it can load videos without the need to the extension.

I noticed that I didn't push the native dylibs after updating the code.

Currently when trying to build using
./gradlew buildNativeLibraries

It throws an error

Related to these lines in NativeVideoPlayer.swift

  var tap: Unmanaged<MTAudioProcessingTap>?
            // Create the audio processing tap
            let status = MTAudioProcessingTapCreate(
                kCFAllocatorDefault, &callbacks, kMTAudioProcessingTapCreationFlag_PostEffects, &tap
            )

Can you check if it builds for you @kdroidFilter ?
