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).

Summary:
I've been seeing a couple crashes related to missing hermes-executor-common.so, seems to happen on specific android versions, but can't repro. I investigated this so file more and noticed it is incorrectly linked as a static library here https://github.com/facebook/react-native/blob/b8f415eb6cdc0e0e7a7413b6f9defdcee304d9e8/ReactAndroid/src/main/java/com/facebook/hermes/reactexecutor/Android.mk#L20. There doesn't seem to be any reason for this to be a shared lib so I changed it to be compiled as a static lib.
## Changelog
[Android] [Fixed] - Make hermes-executor-common a static lib
Pull Request resolved: https://github.com/facebook/react-native/pull/32683
Test Plan:
- Verify there is no more hermes-executor-common-{release,debug}.so
- Test locally in an app to make sure it build and run properly.
- Verify that the crash happening on play store pre-launch report doesn't happen anymore.

Summary:
Ship libjsi as a standalone dynamic library. This prevents problems
with exception handling caused by duplicate typeinfo across multiple
shared libs, and reduces bundle size by removing duplicate copies of
JSI.

Summary:
Microsoft’s RN for macOS fork supports the Hermes engine nowadays https://github.com/microsoft/react-native-macos/pull/473. As a longer term work item, we’ve started moving bits that are not invasive for iOS but _are_ a maintenance burden on us—mostly when merging—upstream. Seeing as this one is a recent addition, it seemed like a good candidate to start with.
As to the actual changes, these include:
* Sharing Android’s Hermes executor with the objc side of the codebase.
* Adding a CocoaPods subspec to build the Hermes inspector source and its dependencies (`Folly/Futures`, `libevent`).
* Adding the bits to the Xcode build phase script that creates the JS bundle for release builds to compile Hermes bytecode and source-maps…
* …coincidentally it turns out that the Xcode build phase script did _not_ by default output source-maps for iOS, which is now fixed too.
All of the Hermes bits are automatically enabled, on macOS, when providing the `hermes-engine-darwin` [npm package](https://www.npmjs.com/package/hermes-engine-darwin) and enabling the Hermes pods.
## Changelog
[General] [Added] - Upstream RN macOS Hermes integration bits
Pull Request resolved: https://github.com/facebook/react-native/pull/29748
Test Plan:
Building RNTester for iOS and Android still works as before.
To test the actual changes themselves, you’ll have to use the macOS target in RNTester in the macOS fork, or create a new application from `master`:
