[rotate] supportedInterfaceOrientations default value is .all

[liamxujia]

Rotating the view to landscape would be a problem, and SwiftEntryKit would pop up portrait and rotate to landscape. I looked at the code, and I created EKRootViewController before EKWindow but when called
rootViewController = rootVC
EKRootViewController will be called
supportedInterfaceOrientations
lastAttributes for nil at this time, so this method returns the default value. The .portrait, now I modified to create supportedInterfaceOrientations returned. The default value is .all, namely screen pop-up view for the first time at this time there will be no problem
