Add a RWH_TabSwitchPaintDuration histogram.
The RWH_TabSwitchPaintDuration histogram calculates
the amount of time it took after a particular view was
selected for it to be fully painted.
Previous versions of this patch included modifications
to the tab switching test. Those are blocked on setting
up a new builder for accurate measurement and are now
removed from this CL.
