I'm marking this as blocking  issue 763452  as there are test utils that wait/sniff compositor frames. Which will no longer be available.

It would be good to know how we can replace these apis. With some api to be notified that they are now in a state which can handle input.

Blocked on surface synchronization because the resize lock stuff in DelegatedFrameHost has to be removed for this task.

Fix race in WaitForResizeComplete

WaitForResizeComplete is racy. Every time RenderWidgetHostImpl receives
a resize ack, it checks whether we're holding pointer moves or not, and
if not reports that resize is completed. However, if releasing pointer
moves happens after the last resize ack, it blocks forever. This race
doesn't seem to happen right now but I have another CL that exposes it.
This CL fixes this issue by adding a callback to WindowEventDispatcher
that would be called when held events are dispatched, which allows
WaitForResizeComplete to block on releasing pointer moves as well.

Surface synchronization: Allocate new LocalSurfaceId on navigation

In order to be able to tell the difference between the graphical output
of the renderer before and after navigation, we should allocate a new
LocalSurfaceId. Currently we rely on content_source_id to achieve this,
but that is not compatible with Viz. When navigation happens, browser
allocates a new id for the child and immediately embeds it. After 4
seconds it drops the fallback SurfaceId if it was generated before
navigation.

Remove RenderWidgetHostLatencyTracker::OnSwapCompositorFrame

This method adds the right component id to snapshot-related latency
info, We can just send the right component id to the renderer so that
a correction browser-side is not necessary.

Test: Lots of pixel tests take screenshots. Also tested
Page.captureScreenshot manually.
