Record first layout time UMA metric in PageLoadHistograms.
Due to the issue described in crbug.com/382542, many histograms
intended to be logged by PageLoadHistograms do not get logged,
because fast shutdown kills processes before they get a chance
to log.
This patch logs first layout metrics earlier in the page life cycle,
in order to avoid losing these histograms.
BUG=507790
