Re-do API

• Re-do APIs so the progress indicator is available directly from the DynamicIsland namespace.

Now, instead of having to subclass a ViewController, you can just use DynamicIsland.progressIndicator from anywhere to control it. This means you can also use it from SwiftUI!

Moving things around

• Rename hasDynamicIsland to isAvailable and move it to the DynamicIsland enum. Now you can do DynamicIsland.isAvailable to check whether you're running on an iPhone 14 Pro or iPhone 14 Pro Max.

Some improvements

• Make dynamicIslandProgressIndicatorConfiguration a property.
• Swap availability check with a hasDynamicIsland check (enforced at runtime when dynamicIslandProgressIndicatorConfiguration is accessed).

A minor bugfix

• Add missing public to the definition of dynamicIslandProgressIndicatorConfiguration(). I am an idiot!
