Summary

Changes the line breaking rules for Japanese to keep natural phrases (of
multiple words) together. In Japanese, this boundary is called "Bunsetu".
Japanese doesn't use spaces to delimit words, and usually prefers to break
at any characters, but short paragraphs such as headlines prefer breaking
at natural phrase boundaries. In CSS, this feature adds a new value to the
`word-break` property: `auto-phrase`. The implementation uses a C++ port of
the BudouX <https://github.com/google/budoux>, the AdaBoost ML technology
to determine the natural phrase boundaries.

Anticipated spec changes

Open questions about a feature may be a source of future web compat or
interop issues. Please list open issues (e.g. links to known github issues
in the project for the feature specification) whose resolution may
introduce web compat/interop risk (e.g., changing to naming or structure of
the API in a non-backward-compatible way).
