HLS packaging does not preserve Dolby Vision metadata

[Viktor]

Summary of the bug:

When remuxing/packaging mkv or ts files with dolby vision (profile 5.1, profile 8.1) dolby vision data is not preserved. As a result file is played (at least by LG C2 TV) as HDR only.

Test file was taken from here: ​https://4kmedia.org/lg-amaze-dolby-vision-uhd-4k-demo/

ffmpeg version: 6.0

How to reproduce:
