VA-API needs AC and DC quant scales for both luma and chroma, and the loop filter level for current frame, but these values are not available outside the private GstVp9Parser structure. And these values may change from frame to frame, so they are picture specific. This patch add GstVp9Segmentation structure array to GstVp9Picture to expose it to derived classes. This approach is safer than passing the parser at picture handling flow. Also, this patch, in order to solve Documentation CI, mark as private the GstVp9Picture structure.
