StaticLayout visual fix for maxLines

When maxLines is set on StaticLayout, the height calculation includes
the lineSpacing for the lastLine, which causes the ellipsized version
and non-ellipsized version to have different heights. With this CL:
* maxLines is always set on StaticLayout
* the correct line count for a given text is preserved, in other words a
  text that would be n lines will not be cut at maxLines.
* The visual height for StaticLayout for ellipsized and non-ellipsized
  cases are the same when maxLines is set.
