Adds a command to set an integer parameter on a RayTracingShader.
Only shaders defined in the .raytrace file can access the int value you designate as the argument for this method. To make this int value accessible to all ray tracing shader types (closest hit, any hit, or miss, for example), call the CommandBuffer.SetGlobalInt method instead.
