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 08b1bffa49715a9615acc025dfbea252d8409e1f.

Film grain support adds a huge amount of overhead to the H264Context
structure for a feature that is rarely used. On low end devices or
pages that have lots of media this bloats memory usage rapidly.
This changes the static film grain metadata allocations to be dynamic
which reduces the H264Context size from 851808 bytes to 53444 bytes.

This allows this common H.274 SEI to be parsed from both H.264
as well as HEVC, as well as probably from VVC in the future.
Generally attempts to keep the original code as similar as possible.
FATE test refererence changes only change the order of side data
export within a single frame. Nothing else seems to have changed.

Defined by H.274, this SEI message is utilized by iPhones to save
the nominal ambient viewing environment for the display of recorded
HDR content. The contents of the message are exposed to API users
as AVFrame side data containing AVAmbientViewingEnvironment.
As the DV RPU test sample is from an iPhone and includes Ambient
Viewing Environment SEI messages, its test result gets updated.
This unfortunately involved adding some parameters
to ff_h2645_sei_to_frame() that will be mostly unused.

It is valid for HEVC; in fact, the ATSC-HEVC spec [1] simply
refers to the relevant H.264 spec.
It is also trivial to implement now: Just move applying AFD
to ff_h2645_sei_to_frame() and stop ignoring AFD when parsing
a HEVC SEI containing it.
A FATE-test for this has been added.

This commit only factors out freeing the common SEI parts,
not whether the fields indicating whether an SEI is present
shall be reset. H.264 and HEVC differ in this regard
(ff_h264_sei_uninit() really resets, whereas ff_hevc_reset_sei()
only uninits.) and neither actually honours the persistency
as prescribed by the relevant specs.
