Revert of Add more trace events to "benchmark" category (patchset #4 id:50001 of https://codereview.chromium.org/855553002/)
Reason for revert:
This CL has perf implication and currently all the android perf bots are red.
So lets delay the landing until we get perf bots back to normal
Original issue's description:
> Add more trace events to "benchmark" category
>
> This is to make the trace events captured during smoothness test more
> useful in debugging smoothness/latency issues.
>
> These added trace events are supposed to be giving most useful information
> about the input/scheduling/rendering pipeline and have low occurrence in
> each frame so as to minimize the performance overhead.
>
> Following are the list for the added trace events roughly in the order
> of the input->rendering pipeline:
>
> LatencyInfo.Flow // so we can follow the input latency flow
> RenderWidgetHostViewAndroid::OnVSync // when frame is started
> InputHandlerProxy::HandleInputEvent // when the input event is handled on impl
> RenderWidget::OnHandleInputEvent // when the input event is handled on main
> Scheduler::BeginFrame // cc decides to schedule a frame
> Scheduler::BeginRetroFrame // cc starts a retro frame
> Scheduler::BeginImplFrame // impl frame is scheduled
> Scheduler::OnBeginImplFrameDeadline // impl frame actually starts
> OnSwapCompositorFrame // browser gets notified that renderer frame is ready
> CompositorImpl::PostComposit // browser schedules a frame
> SingleThreadProxy::CompositeImmediately // browser starts a frame
> SingleThreadProxy::DidSwapBuffersCompleteOnImplThread // browser frame is done
