Add Progress / Continue Watching for movies sets/TMDB Collections

Basically implement a “progress” (replace your username in the URL) page but for movies

So we can both monitor the watch status (and see when a sequel has been released and we watched the earlier movies) and collection status for movies sets/collections.

Movies sets (also known as “collections” as per The Movie Database (TMDB) definition) are essentially grouped movie series.

Current v2 implementation (only for TV shows unfortunately) https://trakt.tv/users/USERNAME/progress (replace your username in the URL)

WIP: progress page for V3 for TV shows : https://github.com/trakt/trakt-web/pull/1982

TMDB Collection bible and definition : https://www.themoviedb.org/bible/collection

Example of a TMDB collection on Trakt v2 : https://trakt.tv/lists/official/the-fast-and-the-furious-collection?sort=rank,asc
