[Internal] [iOS] [Changed] - introduce SKIP_BUNDLING_METRO_IP to skip ip.txt generation

Pull Request resolved: https://github.com/facebook/react-native/pull/31829

Test Plan:
### Classic build will generate ip.txt
```sh
xcodebuild -workspace RNTesterPods.xcworkspace -scheme RNTester -configuration Debug -sdk iphoneos -destination 'generic/platform=iOS'
find $HOME/Library/Developer/Xcode/DerivedData/RNTesterPods-* -name 'ip.txt'
```
this will find the ip.txt

### Specify `SKIP_BUNDLING_METRO_IP=1` will not generate ip.txt
```sh
SKIP_BUNDLING_METRO_IP=1 xcodebuild -workspace RNTesterPods.xcworkspace -scheme RNTester -configuration Debug -sdk iphoneos -destination 'generic/platform=iOS'
find $HOME/Library/Developer/Xcode/DerivedData/RNTesterPods-* -name 'ip.txt'
```
this will NOT find the ip.txt
