78f95f1088 lavfi/dnn: Remove DNN native backend 
According to discussion in
https://etherpad.mit.edu/p/FF_dev_meeting_20221202 and the proposal in
http://ffmpeg.org/pipermail/ffmpeg-devel/2022-December/304534.html,
the DNN native backend should be removed at first step.

e3143703e9 avfilter/vf_libplacebo: strip ICC profiles on CSP change 
Not doing so is an obvious oversight - the ICC profile is tied to the
original colorspace, so if we change it, we should definitely strip this
information.

We should probably also have an extra option to control whether the ICC
profile should be stripped, ignored, or applied, but for now this fixes
an existing bug.

54126920fc doc/filters/libplacebo: add vaapi interop example 
Some testing revealed this to be a very efficient and reliable method of
ingesting GPU frames into libplacebo, so it's a good idea to give as an
example.

4fa691b761 doc/filters/libplacebo: remove outdated example 
This example being first is now misleading because round-tripping
through hwdownload/hwupload is neither required nor recommended. Also,
the comment about avoiding format conversion is unnecessary because
`libplacebo` will now inherit the input frame format by default.

f7d64881f8 mov: Do not blindly disable advanced edit lists if use_mfra_for is set 
This was a bug/mistake in dae3679a9b.

use_mfra_for by defintion only has an effect on fragmented MP4 files,
making the check not only redundant, but also broken if a user used
the option globally (i.e. set on non-fragmented MP4s).

5cdbf817c9 avformat/mov: restrict unix timestamp hack to version 0 mdhd/mvhd 
Commit 23eeffcd48 added a hack to support invalid
files where the creation date was encoded as a classic unix timestamp. Let's
reduce the scope of the hack by only applying it to version 0 mdhd/mvhd atoms.
Also warn the user of such possibly broken files.
