Xcode 14 includes the ability to create single-target watchOS apps without the need for separate app and extension targets, powered by the new WKApplication class.

Some notes about the WKApplication class:

• Looking at the documentation, WKApplication appears to be a direct subclass of UIApplication, with very similar method names. It would not be surprising if WKApplicationMain() was simply calling UIApplicationMain() internally (notably, the principalClassName parameter is missing from WKApplicationMain).
• While the WKApplication class was only added to the public headers in watchOS 9.0 (diff), single-target watchOS apps are supported back to watchOS 7.0, suggesting that this was likely previously private API that Apple has opened to developers.

The following changes need to be made when the deployment target is greater than watchOS 9.0. We can allow the user to manually enable this behavior for deployment targets 7.0 <= x < 9.0.

• AppConverter.swift processInfoPlist() will need to set WKApplication = true and WKWatchOnly = true instead of WKWatchKitApp = true
• AppConverter.swift repackageBundleForWatchOS() can probably become a no-op
• The warning message emitted as part of the conversion process should be changed.

This app really needs an icon.
