Add option to always direct play Dolby Vision Profile 7 (#670)

## Description
A few devices, like the Nvidia Shield Pro 2019, are able to correctly
handle Dolby Vision Profile 7. However, when a Full Enhancement Layer
(FEL) is present, these devices effectively ignore the enhancement layer
and only apply the RPU metadata.

Due to this behavior, device capabilities are reported as not supporting
`DOVIWithEL`, which causes the Jellyfin server to strip the DV layer
entirely with a remux.

This commit adds an option to force direct play of Dolby Vision Profile
7 content, preventing the server from stripping the Dolby Vision layer
and allowing compatible devices to handle playback as intended.
