feat: show mod/VIP badges from shared chats

[jupjohn]

This PR aims to show mod & VIP badges from users in shared chats. It also adds the channel name to the mod/VIP badge's tooltip to further distinguish the source channel.

This can be tested by reverting afbbadb8 and using the /debug-test shared-chat-badge-messages. You may have to run this command twice; the first time seems to not pick up the shared channel's profile picture or name.

TODO: update snapshot tests.

Demo

Chatterino2_6651_SharedChatChannelBadges.mp4

Closes #6651.

I didn't think it was worth adding these to sample data since it's just a test for this PR. If you guys want it added I'm happy to do that, but after I add snapshot tests I don't see a reason to have the messages in the program itself.

I've amended my command commit to target that channel 👍
