Symbolicate unhandled promise rejections (#40914)

Summary:
For a very long time when a promise rejects without an attached catch we get this warning screen without a correct stack trace, only some internal calls to the RN internals.

I created [an issue for discussion](react-native-community/discussions-and-proposals#718) in the react-native-community repo and we figured out it was only a matter of symbolication. While it cannot be done on release without external packages and source maps, at least while developing we can provide a symbolicated stack-trace so developers can better debug the source of rejected promise.

I got the stack trace symbolicated and the correct code frame. I'm missing some help trying to display it in the warning view but at the very least I can now correctly show the line of the error and log the codeframe to the console.
## Changelog:

<!-- Help reviewers and the release process by writing your own changelog entry.

[GENERAL] [FIXED] - Show correct stack frame on unhandled promise rejections on development mode.

Test Plan:
I simply created a throwing function on a dummy app, and checked the output of the console and the warning view:

```ts
import React from 'react';
import {SafeAreaView, Text} from 'react-native';

async function throwme() {
  throw new Error('UNHANDLED');
}

function App(): JSX.Element {
  throwme();

  return (
    <SafeAreaView>
      <Text>Throw test</Text>
    </SafeAreaView>
  );
}

export default App;
```

Here is the output

Edit: I got the warning window working properly:
