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.

Test filtered responses and implement Cors Check Fetch step
I've been writing tests for creating filtered responses. So far I have three of the four types being made (namely, Basic, CORS, and Opaque), and just need to figure out how to make an OpaqueRedirect filtered response, since it's handled separately from the others. I will also add more tests to ensure the content of the filtered responses matches the limitations placed by the specification.
Along the way I implemented Cors Check, since it's required for the CORS filtered response. @jdm suggested I handle it in here, since it's such a small step, compared to other parts of Fetch.
Since all the tests currently pass, and I've spent a while adding the Cors Check and other pieces, I figured now would be a good time to start having it reviewed.

Partial implementation of Main Fetch step
I started out with Step 11 of Main Fetch so I could test creating filtered responses, which broke my tests that compare the Fetch result to a message on a server. I realized that if I got the tests to work, I'd likely end up breaking them again with the next step of Main Fetch I added, so I went ahead and did as much of Main Fetch as I could figure out.
Some steps I'm sure I could implement, I just don't know how. Such as when the spec says to "wait for response", or how to implement a Runnable object (which iirc is what I need to use) to run everything after Step 8 in parallel.
The fetch tests are still not running correctly, but I sure it's because they're getting a filtered response which doesn't have the body of response. I'm not sure how to handle that, whether it means a change needed in the tests or in the Fetch code. Like always, I look forward to feedback on my work!

Implement a basic test for Fetch
As per @jdm's suggestion that I start minimally testing the Fetch protocol to catch any errors, I wrote a very simple test that just calls Fetch and checks that the response isn't a network error. I've made changes as necessary for every failure I encountered, although this doesn't mean the implementation is faultless yet.
As always, I look forward to any feedback for improvements regarding the test itself, the changes to the fetch files I've made, and anything that I missed and should update.

The pipeline id stuff is currently unused. If someone needs it, they can add
an additional trait bound on their css error reporter to get the pipeline id.
Correctly handle local sources for CSS3 fonts
Currently, servo panics for me when loading something like this:
```
@font-face {
font-family: "test family";
src: local(test font face);
}
```
That's due to a bug in `FontCacheTask`. `FontCacheTask` tries to get the value for the key
"test font face" from `self.web_families`, but previously initialized a value for the key "test family".
These two commits add an awkward test and fix the bug by not shadowing the variable `family_name`. Since the argument to `local()` should explicitly not be the name of a font family, the previous variable name was wrong and misleading anyways.

This test tries to add a web font to the `FontCacheTask`. The added web font
corresponds to the following CSS font definition:
```
@font-face {
font-family: "test family";
src: local(test font face);
}
```
This test fails, since `FontCacheTask` tries to get the value for the key
"test font face" from `self.web_families`, but previously initialized
a value for the key "test family".
Refactor AssertRequestsMustNotHaveHeaders
Improve correctness of AssertRequestMustNotHaveHeaders tests
- Changed AssertRequestsMustNotHaveHeaders to AssertRequestMustNotIncudeHeaders
- Added an assertion that headers_not_expected is not empty
tested by command
./mach test unit
and all passed.

This patch does a number of things, unfortunately all at once:
* Hoists a large subset of the layout wrapper functionality into the style system.
* Merges TElementAttributes into the newly-created TElement.
* Reorganizes LayoutData by style vs layout, and removes LayoutDataShared.
* Simplifies the API for borrowing style/layout data.
There's still more to do to make the style system usable standalone, but
this is a good start.
Properly propagate changes when range or trees are mutated
Does the same thing as #6817, but storing Range instances directly in their start and end containers.
