[LayoutNG] Implement line height from font metrics when elements wraps

When elements wraps, 'line-height: normal' should take used fonts of
each line into account, but it was talking used fonts of the element
instead. This patch implements this case using the ShapeResult from
ShapingLineBreaker.

This patch also fixes a case where ShapeResult was not set.
