Enhance CLI validation

[mrmckeb]

Is this a bug report?

No, we've reverted #6080, but want to continue this work in the near future.

Steps to Reproduce

Create an application using npx create-react-app option1 option2 option3. A project called option1 is created, and other arguments are ignored without user feedback.

Expected Behavior

When creating an application with npx create-react-app [options], I should be warned if an option doesn't exist or is invalid.

Actual Behavior

When creating an application with npx create-react-app [options], I can pass in non-existent arguments.

@mrmckeb @iansu I would love to address this. Could you guide me on an effective way to handle those arguments as you intend 🤔
