add customizeStack hook (#36819)

Summary:
Pull Request resolved: #36819

X-link: facebook/metro#964

This diff creates a new hook to the Metro symbolicator. `customizeStack` aims to provide a whole stack modification hook on the output of the `/symbolicate` endpoint.

The purpose of this hook is to be able to apply callsite-based modifications to the stack trace. One such example is user-facing frame skipping APIs like FBLogger internally.

Consider the following API:

```
  FBLogger('my_project')
    .blameToPreviousFile()
    .mustfix(
      'This error should refer to the callsite of this method',
    );
```

In this particular case, we'd want to skip all frames from the top that come from the same source file. To do that, we need knowledge of the entire symbolicated stack, neither a hook before symbolication nor an implementation in `symbolicator.customizeFrame` are sufficient to be able to apply this logic.

This diff creates the new hook, which allows for mutations of the entire symbolicated stack via a `symbolicator.customizeStack` hook. The default implementation of this simply returns the same stack, but it can be wrapped similar to `symbolicator.customizeFrame`.

To actually have information for this hook to act on, I've created the possibility to send additional data to the metro `/symbolicate` endpoint via an `extraData` object. This mirrors the `extraData` from https://github.com/facebook/react-native/blob/main/packages/react-native/Libraries/Core/NativeExceptionsManager.js#L33, and I've wired up LogBox to send that object along with the symbolicate call.

Changelog:
[General][Added] - Added customizeStack hook to Metro's `/symbolicate` endpoint to allow custom frame skipping logic on a stack level.
