Description

This PR adds some logic to the app which switches the user to the Collaboration View when a remote participant (but not the local participant) starts to share their screen. Without this, a user using Grid View would not know that someone else is sharing their screen. Once the user has been automatically switched over to Grid View, they are free to switch back to Collaboration View.

This is the same behavior as what is already implemented in the iOS Video App: https://github.com/twilio/twilio-video-app-ios/blob/67b8494a50eb48568b966aa9cf4c5dea2d327e61/VideoApp/VideoApp/SwiftUI/Screens/Room/RoomViewModel.swift#L88-L118
