…ntil Swift 7 swiftlang#72659 turned out to have some source compatibility fallout that we need to fix. Instead of introducing yet another brittle compatibility hack, stop emitting errors about a missing `any` altogether until a future language mode. Besides resolving the compatibility issue, this will encourage developers to adopt any sooner and grant us ample time to gracefully address any remaining bugs before the source compatibility burden resurfaces. A subsequent commit adds a diagnostic group that will allow users to escalate these warnings to errors with `-Werror ExistentialAny`.
