Add setting to disable custom ffz mod/VIP badges

Pull request checklist:

• CHANGELOG.md was updated, if applicable

Description

Adds a toggle setting that allows disabling using the custom FFZ moderator and VIP badges.
Currently implemented as one setting for both, to avoid more settings, and is enabled by default.

Currently not sure about:

• The location of the setting in the menu and in the settings file.
• Other badge settings update old messages when changed, for example disabling the Chatterino badge setting will remove that badge from already existing messages in chat. However, due to how the current implementation works, this setting doesn't update on old messages, and will only change whether or not the custom badges are used for new messages. Not sure if this is a problem, and if it's worth the effort to make this work when, to my knowledge, there isn't a simple solution that doesn't change the original implementation.

Closes #2693

I'd rather have a dropdown menu where you enable the custom badges.
Something like:
Enable custom FFZ badges for:

• VIP and Moderator
• VIP
• Moderator
• None
  Where VIP and Moderator are default.

(Before you implement it it'd be better if someone else has an opinion on this)

For example I think some of the VIP badges are stupid so I'd make sense to disable them while moderator badges you can always tell that they are moderator badges.

i feel like the "bot" badge from ffz/bttv should be implemented too.

That's a separate issue.

In the long run a dropdown with a string value won't make sense so it's more worth keeping the settings as 'single values', even though it will add a bit more clutter now it can be cleaned up the future if another value were to be added. tl;dr: 2 checkboxes > 1 dropdown menu imo. Setting scope is fine, setting position we've chatted about but it can be added after a separator in the "Visible badges" category

Looks good to me 👌
