Adds a command to set a matrix parameter on a RayTracingShader.
The matrix specified as argument can be used only by the shaders defined inside the .raytrace file associated with the RayTracingShader. If the matrix needs to be visible in all ray tracing shader types (closesthit, anyhit, miss, etc.) then CommandBuffer.SetGlobalMatrixArray or Shader.SetGlobalMatrixArray must be used.
