Warnings have been piling up in the style system, and making it harder to tell when new warnings are introduced. I think we should tighten up on them.

<!-- Please describe your changes on the following line: -->
The goal is to make use of `LengthOrPercentage` for word spacing in `ShapingOptions`, but since it makes use of `f32` which doesn't implement `Hash`, we're going for `NotNan<f32>` from [ordered-float](https://github.com/reem/rust-ordered-float/), which supports hashing. Instead of implementing `Hash` for `LengthOrPercentage` and thereby the inner types like `CSSFloat`, `CalcLengthOrPercentage`, etc., we convert it to `(Au, NotNan<f32>)`.

r? @SimonSapin for the style changes, @Ms2ger or @jdm for the dom and test changes
Source-Repo: https://github.com/servo/servo
Source-Revision: 14aeccc33ab44d706df86fbce67339218efe710c
Background:
The changes to Servo code to support Stylo began in the `selectors` crate with making pseudo-elements generic, defined be the user, so that different users (such as Servo and Gecko/Stylo) could have a different set of pseudo-elements supported and parsed. Adding a trait makes sense there since `selectors` is in its own repository and has others users (or at least [one](https://github.com/SimonSapin/kuchiki)).
Then we kind of kept going with the same pattern and added a bunch of traits in the `style` crate to make everything generic, allowing Servo and Gecko/Stylo to do things differently. But we’ve also added a `gecko` Cargo feature to do conditional compilation, at first to enable or disable some CSS properties and values in the Mako templates. Since we’re doing conditional compilation anyway, it’s often easier and simpler to do it more (with `#[cfg(feature = "gecko")]` and `#[cfg(feature = "servo")]`) that to keep adding traits and making everything generic. When a type is generic, any method that we want to call on it needs to be part of some trait.
----
The first several commits move some code around, mostly from `geckolib` to `style` (with `#[cfg(feature = "gecko")]`) but otherwise don’t change much.
The following commits remove some traits and many type parameters through the `style` crate, replacing them with pairs of conditionally-compiled API-compatible items (types, methods, …).
Simplifying code is nice to make it more maintainable, but this is motivated by another change described in https://github.com/servo/servo/pull/12391#issuecomment-232183942. (Porting Servo for that change proved difficult because some code in the `style` crate was becoming generic over `String` vs `Atom`, and this PR will help make that concrete. That change, in turn, is motivated by removing geckolib’s `[replace]` override for string-cache, in order to enable using a single Cargo "workspace" in this repository.)

This adds support for parsing `@keyframes` rules, and animation properties. Stylo will need it sometime soonish, plus I want to make animations work in Servo.
The remaining part is doin the math and trigger the animations correctly from servo. I don't expect it to be *that* hard, but probaby I'll need to learn a bit more about the current animation infra (e.g. why the heck is the `new_animations_sender` guarded by a `Mutex`?).
I'd expect to land this, since this is already a bunch of work, this is the part exclusively required by stylo (at least if we don't use Servo's machinery), the media query parsing is tested, and the properties land after a flag, but if you prefer to wait until I finish this up it's fine for me too.

The bulk of this is adding cargo features to make derived implementations of `heapsize` and `serde` traits optional.
"Almost" because `std::intrinsics::discriminant_value` is currently unstable and doesn’t have any stable replacement that I know of. For now, this PR conditionally replaces it with `unimplemented!()`.
