SE-0374: Add `sleep(for:)` to Clock

Can the proposed method "back-deploy", by using @available(SwiftStdlib 5.7, *) and @_alwaysEmitIntoClient attributes?
Should the proposed tolerance: Duration? = nil parameter also be added to the existing method on Task?

          /// Suspends the current task for the given duration on a continuous clock.
          ///
          /// If the task is cancelled before the time ends, this function throws 
          /// `CancellationError`.
          ///
          /// This function doesn't block the underlying thread.
          ///
          ///       try await Task.sleep(for: .seconds(3))
          ///
          /// - Parameter duration: The duration to wait.
          @available(SwiftStdlib 5.7, *)
          @_alwaysEmitIntoClient
          public static func sleep(for duration: Duration) async throws {
            try await sleep(until: .now + duration, clock: .continuous)
          }
