2d31d4301d Eliminate duplicate Layout DOM wrappers
There are duplicate sets of Layout DOM wrappers: one for Layout 2013 and
one for Layout 2020. As part of cleaning up and simplifying the
wrappers, this change parameterizes them on the specific layout data
they contain. This allows them to be shared again. In addition, various
small cleanups are included.

Fixes #29691.

404ee8b984 Fix scrolling from script in Layout 2020
Script will only scroll if it detects that an element has a scrolling
box, so this change adds an implementation of the scroll area query to
Layout 2020. This allows some scrolling tests to start passing.

This change also updates all expected results in css-backgrounds and
cssom-view.

3ab5e2a188 Scroll from script should trigger a reflow
Scrolling from script should flow layout and send a display list to
WebRender. This allows all of the scroll nodes to exist in WebRender
before asking it to move the node.

See https://gist.github.com/paulirish/5d52fb081b3570c81e3a.
Fixes #29659.

This change adds support for the <iframe> element to Layout 2020. In
addition, certain aspects of the implementation are made the same
between both layout systems.

6d4b7e7a22 Move hit testing information out of WebRender
Store hit testing information in a data structure that sits alongside
the display list in the compositor. This will allow the compositor to
store more information per-node. The data structure also takes care of
de-duplicating information between successive display list entries. In
the future, the data structure can be even more aggressive in producing
smaller side hit testing lists, if necessary.

41b3726271 feat: shorten thread names
The Linux kernel imposes a 15-byte limit on thread names[1]. This means
information that does not fit in this limit, e.g., the pipeline ID of
layout and script threads, is lost in a debugger and profiler (see the
first column of the table below).

This commit shortens the thread names used in Servo to maximize the
amount of information conveyed. It also rectifies some inconsistencies
in the names.

83fa1b9eaa Cache animation computed values when animations change
Instead of recalculating the animation style every tick of an animation,
cache the computed values when animations change. In addition to being
more efficient, this will allow us to return animation rules as property
declarations because we don't need to consult the final style to produce
them.

9c7b1ae715 layout_2020: Add initial support for getComputedStyle
This implementation is more-or-less on par with the one from layout_2013
and in some cases better. There are still some cases where we don't
return the correct "resolved value," but this is enough to test
animations and transitions.

3a74013abc Start having animations conform to the HTML spec
This is a small step toward fixing #19242. The main idea is that the
clock for animations should advance as the event loop ticks. We
accomplish this by moving the clock from layout and naming it the
"animation timeline" which is the spec language. This should fix
flakiness with animations and transitions tests where a reflow could
move animations forward while script was running.

This change also starts to break out transition and animation events
into their own data structure, because it's quite likely that the next
step in fixing #19242 is to no longer send these events through a
channel.

b585ce5b1f Use a restyle for animation ticks
This change corrects synchronization issues with animations, by
reworking the animation processing model to do a quick restyle and
incremental layout when ticking animations.

While this change adds overhead to animation ticks, the idea is that
this will be the fallback when synchronous behavior is required to
fulfill specification requirements. In the optimistic case, many
animations could be updated and applied off-the-main-thread and then
resynchronized when style information is queried by script.

Fixes #13865.

8f988be18a Add ElementAnimationState and PossibleElementAnimationState
This refactor is preparation for implementing a specification
compliant transitions and animations processing model.

These data structures hold all the animation information about a single
node. Since adding, updating, and modifying animations for a single node
are all interdependent, it makes sense to start encapsulating animation
data and functionality into a single data structure. This also opens up
the possibility for easier concurrency in the future by more easily
allowing per-node mutexes.

Add support for canceling CSS transitions

This change adds support for canceling CSS transitions when a property is
no longer transitionable. Support for canceling and replacing CSS
transitions when the end value changes is still pending. This change
also takes advantage of updating the constellation message to fix a bug
where transition events could be sent for closed pipelines.

Fixes #15079.

Layout viewer for layout 2020

- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors

This PR makes layout 2020 dump the box and fragment tree states into json files that can be visualized with the layout viewer tool. This tool has not much functionality other than displaying these trees and allowing to inspect each node additional data, so there is a lot of room for improvements. Some ideas for follow-ups:

- Make the tool create and display diffs between tree states.
- Actually allow creating new debug scopes during box tree and fragment tree construction. Right now there is a single scope created after constructing both trees, which is not ideal as it only allows looking at the reflow result.
-  Right now an independent JSON file is created per reflow. It would be nice to unify the data obtained on each reflow on a single JSON, so diffs between reflows can be displayed as well.
- Dump and display the DOM tree. Link boxes to DOM nodes.
