Using Intl with standalone Hermes app

👋 I've been experimenting running JS using Hermes as a standalone binary in Linux and wanted to use `Intl.DateTimeFormat`, but looks like `Intl` support is tied to Android/iOS runtimes.

Is there any way to use `Intl` in a Linux runtime without having to use polyfills?

I created this simple gist to reproduce the current `Intl` behavior https://gist.github.com/manuelpuyol/dbb1e41c748dbaf80da3ca3556648611

Start by running the standalone Hermes Linux binary with the linked gist to reproduce the current Intl.DateTimeFormat behavior. Investigate how Intl support is tied to the Android and iOS runtimes; the issue is complete only when the project defines whether and how Intl can work in a Linux runtime without polyfills.
