Allow Applications to use emojis from anywhere

[SemiMute]

This would allow applications to use emojis from any application, or any server without being that application or being in the specific server the emoji is from.

Webhooks do not share this restriction, so it makes little sense to restrict it for bots.

Use-Case:

• For bots who use a large amount of emojis, continuously having to add all development instances and production bot to each server to use the emote can be bothersome.
• For developers that use application emojis, it's annoying to have to fetch 2 different emoji lists (or more depending on if there are multiple developers using different bots) based on the application they are running, e.g a development instance would have to have its own list of emotes. This simplifies it, making it so you only need to upload an emote once.
• Moderation Logs (when messages with external emojis are logged, they won't render, since the bot does not have access to the server)
• Bots that offer 'custom bot' solutions and have custom emotes as part of the main bot.
