Add --api Flag to Create Headless API App with create-next-app

[Arindam200]

What?

Added a new option for create-next-app to create a headless API app. This includes:

• Adding a --api flag for create-next-app to create a headless app.
• Modifying the template to include only the required assets (no public/, app/page.*, etc.).
• Ensuring the app includes only the required dependencies (no @types/react, react, etc.).

Why?

This feature allows users to initialize projects with headless API templates, making it easier to set up projects that require backend functionality without frontend components.

How?

• Added the --api flag to the create-next-app command.
• Modified the template to exclude unnecessary assets and dependencies.

Closes #68118
Closes NEXT-3633
Closes NDX-120
