Convert spec table in CSS pseudo-elements

[teoli2003]

This is part of #1146.

This converts the CSS pseudo-classes to the {{Specifications}} macro.

I left 1 pseudo-elements with the old tables. They are recent additions to the standard and have no bcd entries (not supported anywhere I guess). The tables will be replaced when they get bcd:

• ::cue-region

All other pages look fine, which is really cool! (I thought there were more pseudo-elements, but most of them are not on a standard track!)
