avcodec/dovi_rpuenc: add a flag to enable compression Keyframes must reset the metadata compression state, so we need to also signal this at rpu generation time. Default to uncompressed, because encoders cannot generally know if a given frame will be a keyframe before they finish encoding, but also cannot retroactively attach the RPU.
