Fix a TextIterator crash in Greek text-transform

CSS text-transform can change text length in either ways, resulting in
more or fewer characters in LayoutText. The former case is more well
known and has been largely worked around.

Now that we see the latter case being possible, this patch works around
it in TextIterator to avoid reaching a NOTREACHED().
