Send frame token from viz display with the presentation feedback. This
is more inline with chrome's architecture where viz display service
sends this update.

There are other code paths that used to deliver CompositorFrameMetadata
and they have to call the new path for delivering frame tokens.
Eventually should remove CompositorFrameMetadata code paths.

SynchronousCompositorHost has to ensure tokens are delivered in order.
Previously this worked with metadata version. Now that it's independent,
need to explicitly make sure it's delivered in order.

For now, only call DidProcessFrame. Eventually should move devtools to
frame token and RenderFrameMetadata.
