Better support for Subtitles and Audio Tracks with no title

[iam-best]

Problem description

When adding a Subtitle without a name it looks pretty bad:

If the Subtitle doesn't have a custom title then it should check the language and show a proper title (instead of de it should show German).

For Audio tracks it is better but doesn't show the full language name either. For example German is DEU even though it should be Deutsch or German depending on your App language.

This would save time naming each subtitle and audio track, it would be like on the Jellyfin Website and you would see all subtitle names in your native language (If you speak German the Japanese subtitles would be called Japanisch for example instead of Japanese... Bad example but I hope you get the point).

Proposed solution

Subtitles and Audio tracks should show the complete language name:

de -> German
en -> Englisch
fr -> French
...
