Trigger pepper ViewDidFlushPaint on draw of compositor frame
We now have reliable info about when the compositor finished drawing the last frame, so use that instead of OnSwapBuffersComplete to trigger ViewDidFlushPaint.
This is reliable enough that we don't have to trigger on OnUpdateRectAck when compositing is enabled anymore.
