Support context menus

Summary

Be able to create context menus & listen for them properly

What is the feature request for?

The core library

The Problem

Having a way for users to create and listen for the new context menus natively.

The Ideal Solution

The context menus are somewhat similiar to buttons, and should be created in the same way, if possible.

• Like buttons, context menus are very easily created, even more so than buttons. You can create a simple one with a 2 line POST request. The decorator interface like we have for discord.ui.button could work pretty well for this. The decorator would decorate the callback, and said callback is called when the specific interaction is recieved.
• Buttons also allow for subclassing, which could also be done here. Subclass a ContextMenu class or something of that sort. The subclass will also have an overrideable callback class, just like the button class.

The Current Solution

I’ve managed to get it to work by doing the following:

• Manually registering the command either using aiohttp, or some other way.
• Using on_interaction to listen for incoming interactions, and getting interaction data using interaction.data as the given attributes for interactions won’t always work since the layout of the returned json from Discord is slightly different.

Additional Context

I believe this shouldn’t be too hard to implement, consider it is very similar to buttons, and those were added relatively quickly to the library.

Well well, it’s already in the D.py 2.0 atm 😅

It has already been implemented @itttgg
