Based on feat: Capture app start errors before JS

📜 Description

Adds RNSentrySDK APIs support to @sentry/react-native/expo plugin by importing sentry and adding injecting RNSentrySDK.init/start in the Android MainApplication (Kotlin or Java) or AppDelegate (Objective-C or Swift).

This feature is opt-out to enable it set useNativeInit to true in your @sentry/react-native/expo plugin configuration.

Overall the PR looks good and thank you for the tests!
I still think we could fine tune a bit more the android part and after it we could get ready for merge

[antonis]

Note: The Build & Test / Type Check Typescript 3.8 (pull_request) failure should be fixed when we merge #4673 from main

[lucas-zimerman]

I have re-checked the PR and overall, I only found a nit on a string. After fixing it and if @krystofwoldrich doesn't find anything else, LGTM!

I'm currently updating the base branch with the latest main since there was quite a lot of development that was not synced to the feature branch.

Thank you for the heads up @krystofwoldrich 🙇
I'll update this branch after that along with the review feedback.

Thank you for the fixes. 🚀 It looks great!

Nit. It would be nice to include an example code snippet and a small summary of what will the flag do.
