codecs: vp9decoder: Add segmentation to picture.

Browse source 
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.
