move stylo_test build script guts from Python to Rust
stylo_test's build script is split between Python and Rust. style's
build script already has to perform complicated dances to determine an
appropriate binary to execute, depending on the platform. To avoid
copying and pasting that code, it seems reasonable to simply port the
Python code into Rust, thus making the relationship between generated
files and the cargo dependency output clearer. The new Rust is somewhat
more verbose, but not terribly so.
Doing this makes running `stylo_test` on Windows somewhat easier, as
we don't have to care about the particulars of Python executables. And
more Rust is more better.

WR multi-document update
<!-- Please describe your changes on the following line: -->
The PR updates WR version to support multiple documents (https://github.com/servo/webrender/pull/1509) but doesn't take advantage of this new feature yet.
It also makes Servo to use `DevicePixel` from WR instead of rolling out another one.

Servo's async Tokenizer: New! Improved! Now with multithreading!
<!-- Please describe your changes on the following line: -->
The Tokenizer, defined in the file `async_html.rs` will run on the main thread, while h5e's `Tokenizer`(along with its Sink) lives on the parser thread. Both h5e's `Tokenizer` and `Sink` communicate with the main thread Tokenizer via their own mpsc channels. The Sink keeps sending parser operations to the main thread, to be executed. For some operations, it waits for a message from the main thread before returning.

stylo: Fix compute_squared_distance for AnimatedFilterList
We implement compute_distance for Angle to avoid returning Err(()) from it, and then rewrite compute_squared_distance of AnimatedFilterLIst to avoid using unwrap() and make it simpler.

This only makes use of the "Solid" text decoration type, which
matches the existing support. WR now supports dotted, dashed
and wavy text decorations, but supporting those will need some
extra work in Servo to pass through the correct values.

The alias is left there temporarilly and will be removed completely in a later commit where
also components/style/gecko/generated/structs_{debug|release}.rs are re-generated (they still
use the old alias).
