2fbdad72 - Don't perform `@preconcurrency` typealias adjustments in `@preconcurrency` decls

Don't perform `@preconcurrency` typealias adjustments in `@preconcurrency` decls When a `@preconcurrency` typealias is used within the type of a `@preconcurrency` declaration, such as a function, do not strip concurrency-related types, because the stripping will happen in the outer declaration.
