Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/33396
This commit fully unplugs the `ReactAndroid` from using hermes from the NPM package and plugs the usage of Hermes via the `packages/hermes-engine` Gradle build.
I've used prefab to share the .so between the two builds, so we don't need any extra machinery to make this possible.
Moreover, I've added a `buildHermesFromSource` property, which defaults to false when RN is imported, but is set to true when RN is opened for local development. This should allow us to distribute the `react-native` NPM package and users could potentially toggle which source to use (but see below).
