[tracing] Add latency ids to one of Graphics.Pipeline slices

This CL adds a new latency_ids field to ChromeGraphicsPipeline and
records the latency ids for the corresponding frame for the
Graphics.Pipeline with STEP_GENERATE_COMPOSITOR_FRAME.
This should make it easier to match input to frame production and
presentation.
