feat: opt-in pod install with ios commands

[TMisiukiewicz]

Summary:

Adding new config parameter project.ios.automaticPodsInstallation.

For existing apps, it means developers can opt-in for automatic CocoaPods installation when running run-ios or build-ios. Some projects are running on non-standard setups or pods installation is simply not desired.

For the users using init command starting from 0.73, it will automatically create the react-native.config.js file with this param set to true. File is created by CLI after processing the template.

Test Plan:

1. Create a project with npx react-native init
2. Link the CLI packages following the Contributing guide
3. run-ios and make sure CocoaPods step is skipped
4. Create react-native.config.js file and set project.ios.automaticPodsInstallation to true
5. run-ios again and confirm that CocoaPods are getting installed
6. Create another project with the local CLI node ./path/to/cli init
7. When prompted about pods installation, press n
8. Once project is set, confirm react-native.config.js file exists
9. Run run-ios and verify pods are getting installed

Checklist

• Documentation is up to date to reflect these changes.
• Follows commit message convention described in CONTRIBUTING.md
