Requires a patch to rust-selectors, and doesn't currently recalculate the styles correctly (which is needed to make actual toggling work correctly).
Still trying to figure out what it takes to get style recalc to do what this needs.

Refactor the cascade
Converting the specified value of some properties into a computed value depends on the value of other properties. For example, the `em` unit of any length depends on the `font-size` property.
Previously, we would do a first pass over applicable declarations to build up a `values::computed::Context` struct with a number of fields for each such piece of data from other properties.
This simplies the struct by instead having it contain the set of computed values (for a given element) that is being populated and classify properties into "early" and "other", such that the only dependencies can be from "other" to "early". We iterate applicable_declarations twice, first cascading "early" properties then "other". Unfortunately, it’s not easy to check that this classification is correct.

Add the scrollWidth and scrollHeight extensions to the element interface
Add the `scrollWidth` and `scrollHeight` extensions to the element interface. My goal was to create a method that encompassed getting `scrollWidth`, `scrollHeight`, `scrollTop`, and `scrollLeft`.
I also noted that `clientHeight` and `clientWidth` to not handle the root element and the body element correctly.

Some external dependencies (at least webrender_traits) present only in servo
and not in geckolib use it already and this prevents Cargo to reuse build
artifacts depending on serde between the two targets.
This commit refactors the style crate to be completely independent of
the actual implementation and pseudo-elements supported.
This also adds a gecko backend which introduces parsing for the
anonymous box pseudo-elements[1], although there's still no way of
querying them.
