TimelineName(name, source_type, value_type)
  `Constructs the standard name given in the timeline.
  Args:
  name: The name of the timeline, for example "total", or "render_compositor".
  source_type: One of "cpu", "gpu" or None. None is only used for total times.
  value_type: the type of value. For example "mean", "stddev"...etc.`
