Introduces comprehensive support for creating XR (Extended Reality) experiences directly within Qt Design Studio, enabling immersive 3D workflows and reducing dependency on Qt Creator for design-time tasks

Goals:

• Enable immersive 3D design workflows in Qt Design Studio.
• Provide out-of-the-box support for XR-specific components and interactions.
• Simplify project setup and deployment for XR applications.
• Enhance visual feedback and interactivity during the design phase.

Use cases:

Native XrView Support:

• Replace View3D with XrView as the default for XR projects.
• Ensure compatibility with XR rendering pipelines.

Scene Configuration with xrOrigin:

• Allow setting the xrOrigin type directly in the scene.
• Provide real-time visual feedback for origin placement and orientation.

Immersive Object Placement:

• Simplify the creation and positioning of objects in a 3D XR world.
• Provide tools for spatial manipulation and alignment.

XR Components Integration:

• Support for XrCamera, XrController, and XrInputAction.
• Extend the 2D XR use cases support with XrItem and XrVirtualMouse.

XR Project Wizard:

Create a wizard to scaffold XR projects with:

• A centralized Node containing lights, models, graphics, and animations.
• Quick 3D preview capabilities within Design Studio.
• CMake module structure for downstream integration in Qt Creator.

Direct Device Deployment:

• Add the ability to deploy XR projects directly to devices from Design Studio.
• Eliminate the need for Qt Creator during the design phase.
