Issue: androidx/media#725 Ideally the test to transmux a `ts` file (having 3 bytes NAL start code) should go into `Mp4MuxerEndToEndTest`but `Mp4MuxerEndToEndTest` uses `MediaExtractor` and `MediaExtractor` is returning samples with `4 byte NAL start code` which will not exercise the newly added code path. Hence the test is added in `TransformerWithInAppMuxerEndToEndTest` which internally uses `media3 extractor` and feeds samples with `3 bytes NAL start code` only. PiperOrigin-RevId: 617985866
