Updates the transformation of a ray tracing instance.
For a ray tracing instance associated with a Renderer component, the transformation is retrieved from the Transform component.
For a ray tracing instance associated with a axis-aligned bounding box (AABB) GraphicsBuffer, the handle that was returned by RayTracingAccelerationStructure.AddInstance function should be passed along with a new transformation matrix.
The transformation matrix can be accessed in shader code using WorldToObject() or ObjectToWorld() HLSL functions.
Note that building the acceleration structure on the GPU has to be triggered by calling RayTracingAccelerationStructure.Build or CommandBuffer.BuildRayTracingAccelerationStructure.
