refactor: load Twitch emotes from Helix

[Nerixyz]

It's probably not a fix, but for a user it's a fix.

This PR refactors how Twitch emotes are loaded - using the new Helix API.

As it refactors quite a bit of stuff, it shouldn't be included in the next release.

Although the API returns decent data, it's slow. For my user (two subscriptions), I need to make 28 requests to get all emotes for one channel. One request takes about 100-250ms. Now imagine how long this would take if a user has 50 (or 100) channels open and more subscriptions. I don't think it's my implementation (this would generate a report though the slow HTTP handler alerts).

With this approach we're going to need to use owner_id over emote_set_id, at least for a specific list of channel IDs, otherwise the global tab is going to be even worse than before.

notes:

a cavalcade of funni errors

f5-ing a single channel will label the `Twitch` section of global emotes incorrectly:

loaded naturally

f5 #󠀀1

f5 #󠀀2

emote menu can populate gif emotes twice in some channels (maybe specifically an issue with perma subs)

this does not effect the : menu

I'm hoping for Twitch to utilize the pages better. But we'll still need some rate-limiting.

Fixed by grouping everything to Twitch (no owner-id).

Seems to be twitchdev/issues#922 - I'm hoping this gets fixed - having yet another map to detect duplicates seems pointless. Btw, it's only in the popup.

#5289 - should make sure the emotes listed as well ordered
