Ojan Vafai fc1dff4288 Expose minContentWidth/maxContentWidth and a callback for computing them.
This exposes the last hooks needed to implement flexbox layout. For now,
I didn't worry too much about the exact API we're exposing since this will
all change with the upcoming redesign (e.g. https://codereview.chromium.org/1093633002).

minContentWidth == the width if the element were to wrap at every wrapping point (not including border/padding)

maxContentWidth == the width if the element were to only wrap at hard wrapping points (e.g. \n inside a whitespace: pre).
