style: Support anonymous box pseudo-elements

This is a work-in-progress that:

 * Adds support for some pseudo-elements to skip the cascade entirely, in an analogous way to Gecko's anonymous box pseudo-elements.
 * Takes rid of `StylistWrapper`, and uses `Arc::get_mut` instead.
 * Uses the first bullet to precompute the `-servo-details-content` pseudo's style.

I'd like @bholley to take a look before following, do you think that the aproach is the correct?
Also, @SimonSapin could want to put some eyes on it.

Depends on https://github.com/servo/rust-selectors/pull/81
