Add break-keep utility (#9393)

* ✨ Add `word-break: keep-all` with `keep-all`

ref. https://developer.mozilla.org/en-US/docs/Web/CSS/word-break

`whitespace-nowrap` and `word-break: keep-all` behave differently in different browsers.

Demo: https://jsfiddle.net/h1aj6nvy/

There is a difference between Firefox and Google chrome.

* Rename `keep-all` to `break-keep`
