tdf#113694 Fix BreakIterator_CTL surrogate pairs
BreakIterator_CTL in the non CharacterIteratorMode::SKIPCELL mode did
not handle UTF-16 surrogate pairs at all, causing backspace to delete
lone surrogates which is really bad. Just copied the corresponding code
from BreakIterator_Unicode.
Additionally, BreakIterator_th was not correctly skipping non-Thai text
and always treating one character as Thai.
