cc: Hook vsync time source to output surface
Let the output surface generate a vsync signal for the vsync time
source. This will be used to drive rendering based on a vsync
notification from the browser process.
BUG=149227
TEST=LayerTreeHostTestVSyncNotification
Review URL: https://chromiumcodereview.appspot.com/12674030
