Summary createImageBitmap using a HLS video as source is always black

Seen with bug 231005 MediaPlayerPrivateAVFoundationObjC::paintWithVideoOutput checks that we have a video track before creating an image. However to checks if a video track exists it calls AVAssetTrack* firstEnabledVideoTrack = firstEnabledTrack(safeAVAssetTracksForVisualMedia()); safeAVAssetTracksForVisualMedia queries m_avAsset (a AVURLAsset) for the list of track. However, with HLS the AVURLAsset doesn't contain any tracks, instead they are found in the AVPlayerItem instead.
