avutil/film_grain_params: add metadata to common struct
This is needed for AV1 film grain as well, when using AFGS1 streams. Also add extra width/height and subsampling information, which AFGS1 cares about, as part of the same API bump. (And in principle, H274 should also expose this information, since it is needed downstream to correctly adjust the chroma grain frequency to the subsampling ratio) Deprecate the equivalent H274-exclusive fields. To avoid breaking ABI, add the new fields after the union; but with enough of a paper trail to hopefully re-order them on the next bump.
