Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39540
This simplifies the use of Codegen when creating dev builds of `rn-tester` in the monorepo. It now runs from source for this internal scenario, and this package is now built using the shared monorepo build setup.
Changes:
- Migrate `packages/react-native-codegen` to the shared `yarn build` setup.
- Update package to use `"exports"` field and wrap entry point modules with `babel-register` (NOTE: This is only required for each entry point internally used in the monorepo).
- Fixup small Flow syntax quirks that fail under `hermes-parser`.
- Remove `BuildCodegenCLITask` task from Android build.
- Remove Codegen `build.sh` call from iOS build, use `require.resolve` for `combine-js-to-schema-cli.js` entry point.
Externally significant FYIs:
- `react-native/codegen` is converted to use the `"exports"` field — it should export all `.js` files, as before.
- `codegenPath` is now ignored and marked as deprecated on `ReactExtensions.kt`.
NOTE: TypeScript auto-generation is not yet enabled on this package, since it uses CommonJS `module.exports` syntax (unsupported by `flow-api-translator`).

Summary:
*This is a follow-up to https://github.com/facebook/react-native/issues/28645, redone using a build script based off of Metro's build script instead of using `flow-remove-types` and `flow-copy-source`.*
This pull request adds a build step to `react-native-codegen` that builds the Flow-annotated JS files so that users of the NPM module `react-native-codegen` do not need to use require hooks to be able to import it.
A new build script, `scripts/build.js` is added that builds every JS file in `src/` into a `lib/` folder, and also copies over the original Flow annotated files to `lib/` with a `.js.flow` extension, so users of `react-native-codegen` can still typecheck against it using Flow. The shell scripts in `src` are also copied over. It is based off of the [build script from Metro](https://github.com/facebook/metro/blob/00867816eb9b2f69c8af9cebb523e9e4d280671a/scripts/build.js)
## Changelog
[General] [Added] - Codegen: Add prepublish script to build Flow files
Pull Request resolved: https://github.com/facebook/react-native/pull/28827
Test Plan:
I am able to make use of the Codegen scripts without needing to use the `flow-node` CLI or the `flow-remove-types/register`
require hook.
