Original change's description:
> [scenic] Add trace flow for entire "client present" lifecycle.
>
> Add a "scenic_session_present" flow which has 6 steps:
> - `flatland_present` (on Flatland client thread)
>     - `Present` request is received from Flatland client
> - `acquire_fences_signaled` (on Flatland client thread)
>     - all client `acquire` fences are signaled, so it is OK to incorporate
>       content into global scene graph
> - `request_frame` (on main thread)
>     - schedules a wakeup time for Scenic to begin processing the frame
>       in order to be displayed by the target time
> - `prepare_to_render` (on main thread)
>     - Scenic wakes up, and merges frame changes into the global scene
>       graph before rendering/presenting it
> - `frame_presented` (on main thread)
>     - Frame was displayed on screen.  Scenic is about to notify all
>       clients that requested a present for that frame
> - `flatland_frame_presented` (on Flatland client thread)
>     - the client is about to notified that the content from a specific
>       `Present` request has been displayed
>
> This covers the "life of a Flatland frame" in an intelligible way, and
> provides a good basis for computing performance metrics, versus picking
> "arbitrary" TRACE_DURATION events.
>
> Note: this flow uses the new TRACE_INSTAFLOW_* macros, which means that
> you can search for the flow steps in Perfetto UI using
> "scenic_session_present".
