[CSS Shapes] Simplify LineWidth::wrapNextToShapeOutside()

[CSS Shapes] Simplify LineWidth::wrapNextToShapeOutside()

This function used to manually check to see if the entire height of
the line would have enough space next to the float. However, the code
to compute the offsets will do this automatically (and probably a lot
faster), if the line height is passed in. This patch does just that.
