fix: make method for checking if trait is set

[WoLewicki]

Description

PR exposing a way to check if there was a window trait (status bar or orientation) set by user in any of the navigators. In such case, it should take precedence over other methods, like expo-screen-orientation. Calling

+ (BOOL)shouldAskScreensForTrait:(RNSWindowTrait)trait
                 includingModals:(BOOL)includingModals
                inViewController:(UIViewController *)vc;

should return NO if there was no screen in view hierarchy that requests a specific trait and YES otherwise.

PR to be used e.g. in Expo.

These methods are used by providing their exact signature as a string and therefore their name should not be changed.
