"Ask Copilot" chat feature either in Xcode or in the menubar icon

[cjgaspari]

Really excited for Github Copilot for Xcode. It would be great if users had feature parity with Visual Studio Code, specifically the ability to chat with Copilot for "rubber-duck" sessions. Code completion is great, but sometimes using chat helps to understand things more comprehensively.

While there may be limitations within Xcode to enable a chat interface, I think a nice alternative would be in the menubar where the Copilot icon appears.
