mpegvideo: use the AVVideoEncParams API for exporting QP tables
Do it only when requested with the AV_CODEC_EXPORT_DATA_VIDEO_ENC_PARAMS flag. Drop previous code using the long-deprecated AV_FRAME_DATA_QP_TABLE* API. Temporarily disable fate-filter-pp, fate-filter-pp7, fate-filter-spp. They will be reenabled once these filters are converted in following commits.
