[LayoutNG] Fix font-orientation segmentation

When there are no script segments (i.e., all the text is in
single script) and in vertical flow, we create a single
segment and split it at the font-orientation boundaries.

This patch fixes to create the single segment from the first
text item, not from the first item. If it is created from the
first item and the first item is not a text item, we may give
incorrect script and/or font-orientation to HarfBuzz.
