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.
layout_2020: Add support for transform-style
This requires creating a matching stacking context for every reference
frame and also properly placing those stacking contexts inside them.

Remove a TODO from the implementation of getComputedStyle
The spec is now clear that disconnected elements shouldn't return a
style.

Initiate redirect fetching iff the request has a location
Without this checking, we will run into a TIMEOUT request because
http_redirect_fetch will return immediately when location doesn't exist.

The image cache returns an `ImageCacheResult::ImageAvailable `the second
time you try getting the placeholder. This means that in some cases, the
loading of an image would fail, then the same image would get fetched
from the cache, the placeholder would be loaded from that but would be
seen as a normal image, firing a load event.
This made the tests in
`fetch/cross-origin-resource-policy/image-loads.html` fail depending on
their order.

Add referrerpolicy to list of relevant mutations
<!-- Please describe your changes on the following line: -->
`img.referrerPolicy` change now mutates the image.
Not all `referrerPolicy` attribute changes result in an image update event.
Only valid changes are reflected.
All referrerpolicy tests inside `relevant-mutations.html` WPT test now pass.

./mach test-wpt tests/wpt/web-platform-tests/html/semantics/embedded-content/the-img-element/relevant-mutations.html

This fixes#26388. referrerPolicy is now calls onload for image
mutations. Not all referrerPolicy attribute changes result in an image
update event. Only valid changes are reflected.
Referrerpolicy tests now pass.
Generalize the 2020 regression report to show local unexpected failures
Example usage:
```
./mach test-wpt --release --layout-2020 --log-raw /tmp/servo.log
./tests/wpt/reftests-report/gen.py /tmp/servo.log
firefox ./tests/wpt/reftests-report/report.html
```
Produces a report similar https://community-tc.services.mozilla.com/api/index/v1/task/project.servo.layout-2020-regressions-report/artifacts/public/regressions.html, but showing unexpected reftest failures. The CI-generated one shows Layout 2020 failures (expected or not) that succeed in Layout 2013.
Split animations and transitions into separate lists
This change splits the list of animations and transitions, which are
almost always handled differently. It also renames
`ElementAnimationState` to `ElementAnimationSet` and establishes an
`AnimationState` for every transition and animation. This allows us to
stop continually reallocating lists every time a transition or animation
needs to be canceled.
Fixes#14419.

Have animations more closely match the HTML spec
These two commits do two major things:
**Have animations ticks trigger a restyle**: This corrects synchronization issues with animations,
where the values used in layout are out of sync with what is returned by `getComputedStyle`.
**Tick the animation timer in script according to spec**: This greatly reduces the flakiness of
animation and transitions tests.
Fixes#13865.

This doesn't change any expectation because we're not setting
response.redirected properly so all the tests fail later on when it's
asserted to be true.
Fixes#25257
Workarounds for webxr glwindow on macos
<!-- Please describe your changes on the following line: -->
Makes the default glwindow mode one which does blitting rather than using a shader, since that works on macos.

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.
