Subject: [PATCH] Expose PerformanceObserver related classes in the global
 scope (#45539)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/45539

Changelog: [internal]

This exposes several classes (interfaces in the spec lingo) related to the Performance API to the global scope, so users can access them directly to do things like refinements using `instanceof`. This also prevents the need from importing the modules from `react-native` directly, which would prevent code sharing with Web.
