Implement a WebSocket server for debugging.
<!-- Please describe your changes on the following line: -->
This pull request adds a very simple WebSocket server to Servo, that we intend to use for debugging. It currently only echoes back messages, but eventually we want this server to implement the Chrome Debugging Protocol.

Put back video metadata
I updated the `video-metadata-rs` crate: now, no more ffmpeg, just pure rust. The webm format isn't checked yet.

Response API
<!-- Please describe your changes on the following line: -->
This PR adds the [dom::Response](https://fetch.spec.whatwg.org/#response-class) implementation and addresses #11896.
The relevant passing tests` expectations have been updated.
In order to allow non-UTF-8-encoded status messages, `net_traits::response::Response`'s `raw_status` field has been changed from type [`Option<RawStatus>`](https://doc.servo.org/hyper/http/struct.RawStatus.html) to type `Option<(u16, Vec<u8>)>`. As a result, a few other files which rely on the `raw_status` field were affected and updated.
TODOs:
- The `body` and `trailer` methods. Relies on implementation of `ReadableStream` and `Promise`s.
- Similarly, replace the dummy constructor `_body: Option<USVString>` argument with `body: ResponseBodyInit`.
- Currently, whenever `r's response's header list` or `r's Headers object` are mentioned, I always modify the `headers_reflector` field (of type dom::Headers, or `r's Headers object`) and not the corresponding hyper::Headers list in the net_traits::Response field. A completely accurate interpretation of the spec might consider making both of these lists the same thing via a reference. [Discussion](https://github.com/whatwg/fetch/issues/358) was [had](https://github.com/servo/servo/pull/12884).

Expressions with percentages may be negative or positive at computed value time.
So, we can only clamp lengths at computed value time, which is what the other
browsers do.
Don't use mem::uninitialized() for making calc values
We had code relying on `nsStyleCoord::set()` being leaky (like it was
before we patched up the calc bindings). Added `nsStyleCoord::null()` for
this use case since it's not possible to construct directly anymore.

Update WR + shaders (switch to untyped UBO for CI).
This makes WR startup time significantly faster on Linux, by working around a slow path in the shader compiler.
