Ruslan Mustakov 08a924bcee Proper focus in/out handling on iOS 
PR #18675 (commit 96301e9) revealed a problem with how iOS lifecycle
callbacks were handled by Godot. Before that PR it was possible to get
NOTIFICATION_WM_FOCUS_IN callback without getting the corresponding
NOTIFICATION_WM_FOCUS_OUT. That commit added a flag to ensure they are
always coupled, but now there is an issue when, for example, you open a
notification panel on iOS without moving the app to background.
It resulted in view.stopAnimation being called without the
corresponding startAnimation when the app moves to foreground again, so
it looked like the game hanged.

I changed focus out notification to be sent in applicationWillResignActive,
because it makes more sense than to do it in applicationDidEnterBackground,
because it is always called in pair with applicationDidBecomeActive, where
focus in is sent. applicationDidEnterBackground may not come under
circumstances that are now described as a comment in code.
