Revert "avcodec/h2645: allocate film grain metadata dynamically" 

AVFilmGrainAFGS1Params, the offending struct, is using sizeof(AVFilmGrainParams)
when it should not. This change also forgot to make the necessary changes to the
frame threading sync code.
Both of these will be fixed by the following commit.

H274FilmGrainDatabase will be handled later.

This reverts commit 08b1bffa49.
