Add @sendable attribute to PrefetcherProgressBlock, PrefetcherSourceProgressBlock, PrefetcherCompletionHandler, and PrefetcherSourceCompletionHandler to fix Swift 6 concurrency warnings introduced by PR #2465. These callbacks are invoked across isolation domains (from prefetchQueue to main queue), so marking them @sendable is semantically correct.
