Implement chinese counter styles

Implement chinese counter styles

After r197154 it turned out the counter-style tests [1] do not actually
use cjk-ideographic but rather the explicit chinese styles. This patch
implements the 4 chinese counter styles and adds the tests from the test suite.

This means the previously added tests from css3-counter-styles-081.html
until css3-counter-styles-085.html do not longer need the explicitly
added cjk-ideographic to work.

This patch also changes the suffix for chinese counter styles to match
the spec [2].
