Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/34875
Create common script for generating a Hermes tarball after Hermes is built from source.
Use after building Hermes from source to create a tarball of the resulting build artifacts. The path to the tarball can be passed to CocoaPods via a `HERMES_ENGINE_TARBALL_PATH` envvar in order to use these pre-built Hermes artifacts when installing the `hermes-engine` pod with `pod install`.
Use in Circle CI when creating a Hermes tarball for caching and for use in stable React Native releases.
Usage:
```
pod install
# When Hermes is built from source via CocoaPods, the build artifacts will be located in the Pods directory for hermes-engine
node ./scripts/hermes/create-tarball.js \
--inputDir ./sdks/hermes \
--buildType Debug \
--releaseVersion 1000.0.0 \
--outputDir .
```
