Feature Request: Add support for SMTC/MPRIS

(similar to https://support.discord.com/hc/en-us/community/posts/360062711132-MPRIS-support-for-music-playing)

So, Spotify's "Listening to" integration works (and it works really well, don't get me wrong), but it only really supports Spotify. You can use some third-party apps/plugins to add RPC support for whatever music player you have (think of PreMiD's YouTube Music, theLMGN's SMTCRP or ToppleKek's discord-rhythmbox-plugin) but, let's be honest, those are inconvenient. Why wouldn't Discord be able to directly read SMTC (for Windows) or MPRIS (for Linux) tags directly for the user and set that to its activity?
(minus the album artwork because i can very clearly see how that can go wrong, someone in a server could say "click my profile" and it'd show cropped nsfw with a song that has a NSFW title and stuff)
