Support state restoration with ORKOrderedTaskView

Problem

Within the ResearchKitSwiftUI target we implement the ORKOrderedTaskView to natively use the ORKTaskViewController within SwiftUI environments. Basic functionality is supported by the ORKOrderedTaskView.

A handy feature supported by the ORKTaskViewController is to initialize the view controller with restoration data (see initWithTask:restorationData:delegate:.

Solution

The ORKOrderedTaskView should support to declare support for save and restore (see taskViewControllerSupportsSaveAndRestore:) and forward the restoration Data to the result closure respectively. Additionally ORKOrderedTaskView should receive an additional initializer (argument) to be initialized from a given Blob of restoration data.
