Subject: [PATCH] feat(scripts): Support multiple bundles in
 react-native-xcode.sh (#46339)

Summary:
This enables projects to have multiple bundles built during the Xcode bundling phase (e.g. for projects where you might have a PhoneScene and a CarPlayScene each with their own RootView and bundle, if you're using [react-native-carplay](https://github.com/birkir/react-native-carplay)).

## Changelog:
[IOS] [ADDED] - User-configurable BUNDLE_NAME when building bundles

Pull Request resolved: https://github.com/facebook/react-native/pull/46339

Test Plan:
Built my project with the following Xcode "Bundle React Native code" build step:
```sh
set -e

export SOURCEMAP_FILE="$(pwd)/../main.jsbundle.map";
SOURCEMAP_FILE="$(pwd)/../main.jsbundle.map"

WITH_ENVIRONMENT="../node_modules/react-native/scripts/xcode/with-environment.sh"
REACT_NATIVE_XCODE="../node_modules/react-native/scripts/react-native-xcode.sh"

/bin/sh -c "BUNDLE_NAME=main $WITH_ENVIRONMENT $REACT_NATIVE_XCODE"
/bin/sh -c "BUNDLE_NAME=carplay $WITH_ENVIRONMENT $REACT_NATIVE_XCODE"
```

Then launched the app with a modified `AppDelegate.swift` which loaded main.jsbundle into one RootView and carplay.bundle into another RootView.
