Color Management: Remove "High Dynamic Range" setting

This was a temporary solution until we had proper HDR displays.

* Auto detect from the display + view transform if they are HDR, and
  enable it automatically. This is based on encoding hdr-video in the config.
* If a HDR transform is selected and there is no HDR display support, an
  info message will be shown in the color management panel.
* It is now possible to view HDR images in the image editor, without
  needing to use "View as Render".
* There is no versioning to switch to a HDR display, because that also
  affects image saving. So users will have to manually select the
  "Rec.2100 PQ" display to see HDR colors again.
