DevMenu differences iOS/Android when using Hermes

[henrymoulton]

Description

When using Hermes, iOS has a different DevMenu to Android:

iOS:

Android:

This is important, when clicking Debug the Android app will crash if using Reanimated 2 "As the library uses JSI for synchronous native methods access, remote debugging is no longer possible. You can use Flipper for debugging your JS code, however connecting debugger to JS context which runs on the UI thread is not currently supported."

It's a much better developer experience as well to open Flipper.

This is also an issue when the Android device launches with Debugging enabled. It will automatically crash with
