This change updates the CJK BreakIterator to run ICU line breaking rules
after applying user forbidden rules. This fixes several identified CJK
GUI text rendering issues, most significantly that embedded English runs
were previously broken using CJK break rules, rather than using the
correct English rules.
By implementing this fallback to the ICU rules, the CJK BreakIterator
now also correctly handles non-breaking characters. This change
therefore also fixes tdf#117554.
