Implement the remainder of the amendment to SE-0306 "Actors" that considers any reference to an actor-isolated `let` from within a different module like a (mutable) property reference. If such references are from outside the actor, it will be a cross-actor reference at will be implicitly `async`.
A nonisolated declaration is accessible concurrently, so it must be of Sendable type to be safe. This plugs a hole in data-race preventation that will need to be documented in an amendment to SE-0313.
