Reviewed by Myles C. Maxfield.

Add all non-ethiopian WebKit-only counter styles into counterStyles.css.
Some are sourced from https://www.w3.org/TR/predefined-counter-styles/ , some other are sourced directly from RenderListMarker.

All the ported counter-styles are covered by layout tests in fast/lists/.

Ethiopian counter styles haven't been ported because of some inconsistencies between the W3C predefined counter styles and the WebKit implementation.
rdar://108704382 has been filed to port those.
