Fix most typoes for: "referer" -> "referrer"
Replace most uses of the word "referer" with "referrer", except for `hyper::header::Referer`. Also update the unit tests to compile & pass after those changes.

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).

Handle specialized serialization of <position> in basic shapes
Fixes#13083
We temporarily broke basic-shape serialization in #13042 when 4-value positions were implemented, since I didn't want to increase the scope of that PR too much.
This fixes it.

The style candidate cache had regressed a few times (see #12534), and my
intuition is that being able to disable all style sharing with a single rule in
the page is really unfortunate.
This commit redesigns the style sharing cache in order to be a optimistic cache,
but then reject candidates if they match different sibling-affecting selectors
in the page, for example.
So far the numbers have improved, but not so much as I'd wanted (~10%/20% of
non-incremental restyling time in general). The current implementation is really
dumb though (we recompute and re-match a lot of stuff), so we should be able to
optimise it quite a bit.
I have different ideas for improving it (that may or may not work), apart of the
low-hanging fruit like don't re-matching candidates all the time but I have to
measure the real impact.
Also, I need to verify it against try.
style: Add support for parsing and serialization of <basic-shape>s
Still WIP: I still need to use this somewhere and make serialization minimal. I'm not sure if I should do either in this PR.
The only other browser that handles basic shapes doesn't serialize correctly either (https://bugzilla.mozilla.org/show_bug.cgi?id=1290864), so that's not something we need to get done now.
As far as using this somewhere, I have the following options:
- Merge this now, work on using it in stylo in a followup.
- Just write extensive unit tests for parsing/serialization for now (stylo in a followup)
- Use this for clip-path in stylo only (which I intend to do anyway, just not sure if I should do it in this PR)
- Use this for clip-path in Servo (I'd rather not do this; this would be a huge change requiring a lot more layout knowledge than I currently have)
Thoughts? Review? @SimonSapin @bholley
