Change default Japanese fonts on OS X from Pro to ProN

OS X has contained Hiragino Kaku Gothic/Mincho ProN fonts which adapt JIS X 0213:2004 glyph forms and used them since 10.5. This CL makes Chromium use ProN fonts instead of Pro fonts.

This is in line with Firefox and Safari.

BUG=447843
TEST=On OS X, ProN fonts are used (per dom inspector).
