Remove recently unused CTLScriptType code

This is now unused after:

commit 98f7ec383db74a6491e925e30125d3fbf270afc2
Author: Khaled Hosny <khaled@libreoffice.org>
Date:   Sun May 28 16:28:52 2023 +0300

tdf#139863, tdf#155514: Don’t split COMPLEX text portions

The code is also broken as it doesn’t handle surrogate pairs.

The UNO API now throws an exception.
