New user preference to force enable or disable common HDR and Dolby Vision formats (#1644)

Browse source 
Description
Adding per-format HDR override preferences (HDR10, HDR10+, Dolby Vision
Profile 5/7/8) to control device compatibility information sent to the
Jellyfin server, so users can force specific formats on or off
independently instead of disabling Dolby Vision as a whole.

Related issues
This is a common problem across the Jellyfin ecosystem, but there isn't
a specific issue for Wholphin. My experience is the issue is FireTV
(model and generation) + TV dependent + media dependent. I tested videos
from
https://kodi.wiki/view/Samples with the same DOVIWithHDR10 flag that
worked while other movies I have with It is a very frustrating user
experience and the current workaround of setting the bitrate really low
to force a transcode is sub-optimal IMO as it lowers the video quality.
This allows the user to maintain full quality while disabling only the
specific format(s) causing problems.
