UIApplication based status bar style APIs are deprecated in iOS 9 and iOS 13, see #128730

We should update to use the view controller based status bar.

The tasks includes:

• Update the engine code to use the view controller status bar APIs for newer iOS versions, keep the UIApplication based code. (done in [ios] view controller based status bar engine#42643)
• Update the info.plist template so that UIViewControllerBasedStatusBar is true.
• Update UIViewControllerBasedStatusBar to be true for all the examples apps in packages, framework and engine
  - [ ] ??Add a migration so all the existing Flutter apps will have UIViewControllerBasedStatusBar to be true. (We need to evaluate if we should do this)
