Summary:
This PR introduces the `vision` interfaceIdiom to check if the app runs on visionOS.
An update to the documentation should follow this change.
## Changelog:
[IOS] [ADDED] - Introduce `vision` interfaceIdiom
Pull Request resolved: https://github.com/facebook/react-native/pull/42243
Test Plan: This change has been used in `react-native-visionos` and the interfaceIdiom changes **only** when running in the non-compatibility mode. But it's still useful to have this upstream if at some point React native would compile to visionOS natively
