video stream resync/vout can't be reused fast enough.

Code relying on AVX-2 (like dav1d) cannot work without an alignment of 32 bytes
at least. Even avcodec has a requirement of 64 (likely to get at least 32 on all
planes). So it's probably time to upgrade.

picture_Setup ensures a horizontal alignment to 32 bytes and a vertical to 16
bytes. So for all buffers allocated by the core, we have a size multiple of 512
bytes.

It is more consistent with the way of using/defining enums in the rest of the libvlc API.

Fix #17368

ref #17368

This API is mostly meant to simplify thumbnailing management, by
exposing a simple picture type, that can be probed for its buffer or
saved to a file

dav1d may return the same buffer/picture_t multiple times. In that case we
can't output the same picture_t pointer multiple time, so we clone it
every time.
