43e63ff20a avcodec: move content light level SEI handling to h2645_sei
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.

5de565107a avcodec/h2645_sei: add support for Ambient Viewing Environment SEI
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.

7b450bafd7 avcodec/h2645_sei: Factor attaching film grain side-data to frame out
This unfortunately involved adding some parameters
to ff_h2645_sei_to_frame() that will be mostly unused.

a5bba606a0 avcodec/h2645_sei: Also support Active Format Descriptor for HEVC
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.

f89825e60a avcodec/h2645_sei: Factor out freeing common SEI parts
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.
