word-break: keep-all incorrectly suppresses break opportunities at CJK
punctuation
https://bugs.webkit.org/show_bug.cgi?id=312099
Reviewed by Antti Koivisto.
Per CSS Text 3, keep-all suppresses soft wrap opportunities between
typographic letter units only. It is "otherwise equivalent to normal",
meaning punctuation break opportunities should still work.
The KeepAll shortcut for 16-bit text used nextBreakableSpace() which
only finds spaces. CJK punctuation like U+3001 (ideographic comma)
was ignored.
The fix adds a PunctuationBreaks template parameter to
nextBreakableSpace. When enabled (KeepAll + 16-bit text), it also
breaks after punctuation characters using Unicode General Category.
