Jason Simmons b2f8ce750a libtxt: track the font metrics of each run in order to calculate heights in GetRectsForRange (flutter/engine#4442)
Previously GetRectsForRange was assigning each rectangle a height matching the
height of the entire line.  If the line includes multiple text styles, callers
will expect each span's rectangle to reflect the height of that span.
