ui/nvenc: Export bitrate for OBS Studio to use

Browse Source 
This should improve Replay Buffer and Low Latency Networking code, which may result in drastically better streaming with less dropped frames. I don't know why OBS Studio does it this way instead of just calculating the true kbit/sec bitrate by itself, but I guess this is just another case of "it works so it stayed in".
