Support Slide Over and Split View on iPad (#36255)

Summary:
Context: We have been looking at more multi-window on iPad bugs and issues for React Native. One is that the default test app currently doesn't support SlideOver / Split View / MultiWindow. This change should support the first two of those configurations.

This mirrors a change we had done in React Native Test App: microsoft/react-native-test-app#1032
In order to support Slide Over and Split View on iPad, the app must support all 4 orientations.

Note, this does not support multi-window, which would require RNTester to be refactored to use a `SceneDelegate`. React Native Test app already does this: https://github.com/microsoft/react-native-test-app/blob/trunk/ios/ReactTestApp/SceneDelegate.swift

## Changelog

[INTERNAL] [CHANGED] - Support Slide Over and Split View on iPad for RNTester

Pull Request resolved: #36255

Test Plan:
Ran RNTester and tested both configurations.
