Intl.NumberFormat does not interpret strings as decimal

### Description

In modern browsers, you can pass strings to Intl.NumberFormat.format so that you do not lose precision. This is especially important when formatting financial information.

### Steps to reproduce

Run the following on React Native:
```
console.log(
new Intl.NumberFormat('de-DE', { style: 'currency', currency: 'EUR' }).format(
"999_999_999_999_999_999_999_999_999_999".replaceAll("_",""),
),
);
```

It outputs (on Android and iOS):
`1.000.000.000.000.000.000.000.000.000.000,00 €`
If you run the above code snippet in a browser it will output:
`999.999.999.999.999.999.999.999.999.999,00 €`

Start by running the provided Intl.NumberFormat example with Hermes in React Native 0.73.6 on iOS and Android, then compare its output with a modern browser. Trace the string-formatting path responsible for the precision difference. Done means large decimal strings produce the same precise formatted value as the browser without being rounded.
