Create a sample app to measure performance and measure how embedding Sentry affects performance

### Problem Statement

The issue came from here: [https://github.com/getsentry/sentry-react-native/issues/5121]()

The idea here is to create a heavy (close to real) app with a list of dynamically loaded items, and add measurements on how adding Sentry affects performance there.
Another idea is to simply use [https://github.com/sentry-demos/sentry_react_native]() as a base and add more sophisticated logic on top of it.
