Remove -webkit-hyphens and -webkit-hyphenate-limit-* properties.

Remove -webkit-hyphens and -webkit-hyphenate-limit-* properties.

-webkit-hyphens was only partially implemented and the
-webkit-hyphenate-limit-* properties help to control the unimplemented
parts of -webkit-hyphens.

We still support ­ (soft-hyphens) and -webkit-hyphenate-character.

Test changes:
- Rewrote hyphen-min-preferred-width to use ­ instead of -webkit-hyphens:auto.
- Rewrote hyphenate-character.html so it's a reftest and uses ­.
- Removed a -webkit-hyphens: none; test case from soft-hyphen-min-preferred-width.html.
