avcodec/libsvtav1: signal CPB properties through side data 

This way values such as maxrate/bufsize can be utilized further
down the chain.

First, syncs up the max_rate and buffer_size from SVT-AV1 back to
avctx, and then in case at least one of the utilized values is
nonzero, adds the CPB properties side data.
