refactor(iOS): remove unintended flags from build-ios

[thymikee]

Summary:

The build-ios command contained some left-over flags from run-ios like simulator, uuid, device. Removed the references and moved the code a bit to remove duplication.

As a followup we should focus on bringing interactive behavior as default

Test Plan:

Checklist

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

Great cleanup! 🙌 I still see some flags such us --binary-path or --list-devices under build-ios command instead of run-ios in docs ;/ We need to fully sync docs with codebase.
