Stop encoding/decoding presentation time as part of the message. What's actually in emsg boxes is a presentation time delta, which is why it's only 32 bits, and hence why it doesn't handle large absolute timestamps. We were using this field to hold absolute timestamps only for the purpose of passing presentation times from DashManifestParser.parseEvent back to the calling method. After this change, we return Pair<Long, EventMessage> instead. Issue: #5490 PiperOrigin-RevId: 233561731
