r? @jdm
I ran some tests at random from the `navigating-across-documents` folder, and they are passing.

Implement "update the image data"
<!-- Please describe your changes on the following line: -->
Spec compliant implementation of the [update the image data algorithm](https://html.spec.whatwg.org/multipage/embedded-content.html#update-the-image-data).
Currently still a work in progress, the ['async src complete test`](https://github.com/servo/servo/blob/master/tests/wpt/web-platform-tests/html/semantics/embedded-content/the-img-element/img.complete.html#L33) is still passing as it was before, even though I switched to the new code, so I guess that's something.
@jdm I will be picking this up next weekend, I left a bunch of TODO and NOTES in the code, if you or someone else have time this week I would appreciate an initial scan and feedback.

Webdriver browsing contexts not pipelines
<!-- Please describe your changes on the following line: -->
At the moment, a webdriver session stores a `pipeline_id`s, which causes a mismatch with the spec, which asks a session to store a browsing context and a top-level browsing context. This PR fixes this mismatch.

Adjust the matching process to look for a "relevant link" while matching. A
"relevant link" is the element being matched if it is a link or the nearest
ancestor link.
Matching for links now depends on the `VisitedHandlingMode`, which determines
whether all links match as if they are unvisited (the default) or if the
relevant link matches as visited (and all others remain unvisited).
If a relevant link is ever found for any selector, track this as part of the
`MatchingContext` object. This is used in the next patch to determine if an
additional match and cascade should be performed to compute the styles when
visited.

Bug 1270740 - remove requestAutocomplete reference
<!-- Please describe your changes on the following line: -->
I was in charge of removing the `requestAutocomplete` feature in [mozilla-central](https://bugzilla.mozilla.org/show_bug.cgi?id=1270740), and needed to remove a reference to that feature in the **servo** comments. The change, therefore, is really trivial.

Use microtasks to await a stable state.
<!-- Please describe your changes on the following line: -->
@jdm @KiChjang First pass at using microtasks to await a stable state. I ran into all sorts of problems to get it to compile, I think it's mainly related to the fact that the microtasks are stored in a `Vec`, which meant the `Runnalbe.handler(self: Box<Self>)` couldn't be called while iterating over the Vec... It compiles now although I haven't run any tests. I'm assuming I'm missing something fundamental and was hoping my changes would highlight the problems I run into, and you had a better idea of how to implement this... Perhaps we shouldn't pass a `Runnable` to `await_stable_state` at all?

Avoid returning / passing around a huge ParsedDeclaration type
This enum type used to contain the result of parsing one CSS source declaration (`name: value;`) and expanding shorthands. Enum types are as big as the biggest of their variant (plus discriminant), which was quite big because some shorthands expand to many longhand properties. This type was returned through many functions and methods, wrapped and rewrapped in `Result` with different error types. This presumably caused significant `memmove` traffic.
Instead, we now allocate an `ArrayVec` on the stack and pass `&mut` references to it for various functions to push into it. This type is also very big, but we never move it.
We still use an intermediate data structure because we sometimes decide after shorthand expansion that a declaration is invalid after all and that we’re gonna drop it. Only later do we push to a `PropertyDeclarationBlock`, with an entire `ArrayVec` or nothing.
In future work we can try to avoid a large stack-allocated array, and instead writing directly to the heap allocation of the `Vec` inside `PropertyDeclarationBlock`. However this is tricky: we need to preserve this "all or nothing" aspect of parsing one source declaration, and at the same time we want to make it as little error-prone as possible for the various call sites. `PropertyDeclarationBlock` curently does property deduplication incrementally: as each `PropertyDeclaration` is pushed, we check if an existing declaration of the same property exists and if so overwrite it. To get rid of the stack allocated array we’d need to somehow deduplicate separately after pushing multiple `PropertyDeclaration`.

Implement WebGL extensions
<!-- Please describe your changes on the following line: -->
This PR provides the base for implementing WebGL extensions. It comes with the following ones already implemented and passing all related WebGL conformance tests:
- OES_texture_float
- OES_texture_float_linear
- OES_texture_half_float
- OES_texture_half_float_linear
- OES_vertex_array_object
I'll submit other extensions like compressed textures in a separate PR to ease the review process. I included the 5 extensions in this PR because it's easier to show/review how the WebGL extension base works.
To pass all OES_texture_float_xxx tests I had to add some missing format conversions in WebGLRenderingContext.rs

Renamed constellation::Frame to constellation::BrowsingContext
<!-- Please describe your changes on the following line: -->
Now that script has `WindowProxy` rather than `BrowsingContext` objects, we can rename `Frame` in the constellation to `BrowsingContext`. In particular, this means that `FrameId`s are now `BrowsingContextid`s, which better captures their purpose (and they are used in a lot of places, not just the constellation).

Create a MatchingContext to group related matching args
https://bugzilla.mozilla.org/show_bug.cgi?id=1364914
Upcoming changes for visited support and others as well need to pass more args through matching, so this creates a MatchingContext to group them together.

Scroll roots are no longer nested containers holding items, so instead
we need to track the offsets of each, carefully handling fixed position
items and stacking contexts that create new reference frames.
Additionally, we remove the complexity of the pre-computed page scroll
offset, instead opting to send script scrolls to the layout task in
order to more quickly have a ScrollState there that matches the
script's idea of the scroll world.
Fixes #16405.
