Subject: [PATCH] - Allow overriding ENTRY_FILE on react-native-xcode.sh script
 (#23667)

Summary:
1. Feature parity with Android, that already have this extensibility point on `build.gradle`:
https://github.com/facebook/react-native/blob/7c9805ce163c5a027da2b8458e87d9b582ba9ba6/react.gradle#L12

2. Helps with using react-native on a monorepo project (yarn workspaces) without having to use the no-hoist feature (e.g. in my case the `ENTRY_FILE` is on `root/packages/mobile/index.js` instead of `root/index.ios.js`)

[iOS] [Added] - Allow overriding ENTRY_FILE on react-native-xcode.sh script
