[screen-orientation] Integrate ExpoReactDelegateHandler to support auto setup on iOS (#15140)

# Why

saving expo-screen-orientation from [config-plugins dangerous mod](https://github.com/expo/expo/blob/a3f4993b085cdde19981e6240342df5368c0b507/packages/expo-screen-orientation/plugin/src/withScreenOrientation.ts). also saving from the tricky workaround for expo-updates on sdk-43: #15100
close ENG-2443

# How

- integrate with `ExpoReactDelegateHandler`
- Introduce `initDefaultScreenOrientationFromPlist` and update config-plugin to mutate plist value instead of dangerous mod.

# Test Plan

bare-expo + NCL
