  [Cocoa] Hook up word-boundary-detection to CFStringTokenizer
https://bugs.webkit.org/show_bug.cgi?id=257933
<rdar://problem/110563559>

Reviewed by Tim Nguyen.

We added parsing support so that we can hook it up to CFStringTokenizer, which provides
a linguistically-sophisticated line breaking algorithm. This patch simply hooks them up
together.

The behavior differences are extremely minor right now, because Core Foundation is still
working on rdar://problem/110235041. When they fix that, WebKit will automatically
progress.
