XR raycast subsystem

Raycasts allow you to perform hit testing against AR-specific features. They use the same concept as the Physics.Raycast, but raycast targets don't require a presence in the physics world.

There are two types of raycasts:

• Screen point
• Arbitrary ray

Some implementations only support one or the other. You can check for support with XRRaycastSubsystemDescriptor.
