"Tried to clone a value backed by a different Runtime" on Hermes/iOS

[mrousavy]

When enabling Hermes on iOS, ShareableValue::adapt crashes with the error

Tried to clone a value backed by a different Runtime

This is a SIGABRT and unfortunately really hard to debug. So I have no idea what's causing this.

This is only happening on Hermes + iOS. JSC + iOS, JSC + Android and Hermes + Android works fine. 🤨
