Implement exception groups (AggregateError)

### Description

React Native SDK currently supports linked exceptions using [`cause`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error/cause) but doesn't support [AggregateError](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/AggregateError).

### Notes

- Implementing this might likely change grouping so it should be done in a major version.

### Works
```json
{
"message": "Third",
"cause": {
"message": "Second",
"cause": {
"message": "First",
}
}
}
```

### Not implemented at the moment
```json
{
"message": "Third",
"errors": [
{
"message": "First",
},
{
"message": "Second",
},
]
}
```

No se nombra ningún archivo de implementación, prueba ni punto de entrada. Empieza leyendo el RFC de exception-groups enlazado, las referencias de AggregateError y el pull request relacionado de sentry-javascript, y revisa la incidencia bloqueante de Sentry. Se considera terminado cuando los eventos de React Native representan AggregateError's errors array de forma coherente con el ejemplo documentado y se han abordado las implicaciones para la agrupación.
