Owned media indicator on posters and media pages

Add an indicator on media a user owns, shown on the poster or on the media page itself, similar to the "Watched: 2" indicator. For TV shows it could read "Owned: 100%" or "Owned 218/218", where the percentage / numbers indicate the amount of episodes owned. When browsing other media pages and it's just an icon on the poster, it could be a little book (or whatever icon represents the library) with half filled vs fully filled states, like the check mark icon currently does. Movies are binary, since that's just "do you or do you not have it". Context: the Library function displays every individual episode for shows, is not easy to look at, and currently isn't sortable at all.
