Improve Copilot integration with QtCreator - Chat features and opened files context

It would be great that Copilot integration with QtCreator will be improved in future releases like in VSCode.

• suggestions right now are quite fine, but from the experience that I have there's no context awareness of all the opened files (c++ or qml).
• There're no chat features available that would be useful for different use cases. (in VSCode is used the GitHub Copilot Chat - Visual Studio Marketplace )
