In quirks mode, preserved segment breaks should add line height to
lines. This matches the behavior of WebKit and Blink, but not Gecko.
This also handles the special-case of `<br>` elements, which are
implemented with preserved segment breaks via `white-space: pre-line`.
This is an implementation detail though because `<br>` has a special
behavior if the line isn't empty -- it doesn't add any line height in
this case.
Absolutes need to be placed at their hypothetical position as if the
position value was static. This position differs based on the value they
had before blockification. The code for placing absolutes was taking
into account the original display for the inline value, but not for the
block value. A static `display: block` box would placed at a new block
position past the end of the linebox.
As per HTML [1], <div align="..."> and <center> should behave as if they
had the text-align property set to the corresponding value.
Servo implements that as internal text-align values because there should
the extra effect of aligning block descendants, but that part has not
been implemented yet. This patch only adds support for inline layout.

* script: Do not run layout in a thread
Instead of spawning a thread for layout that almost always runs
synchronously with script, simply run layout in the script thread.
This is a resurrection of #28708, taking just the bits that remove the
layout thread. It's a complex change and thus is just a first step
toward cleaning up the interface between script and layout. Messages are
still passed from script to layout via a `process()` method and script
proxies some messages to layout from other threads as well.
Big changes:
1. Layout is created in the script thread on Document load, thus every
live document is guaranteed to have a layout. This isn't completely
hidden in the interface, but we can safely `unwrap()` on a Document's
layout.
2. Layout configuration is abstracted away into a LayoutConfig struct
and the LayoutFactory is a struct passed around by the Constellation.
This is to avoid having to monomorphize the entire script thread
for each layout.
3. Instead of having the Constellation block on the layout thread to
figure out the current epoch and whether there are pending web fonts
loading, updates are sent synchronously to the Constellation when
rendering to a screenshot. This practically only used by the WPT.
A couple tests start to fail, which is probably inevitable since removing
the layout thread has introduced timing changes in "exit after load" and
screenshot behavior.

This adds basic support for `text-transform` in a way that is more
complete than legacy layout. There are still many missing elements of
proper `text-transform` support such as:
1. Support for `full-width` and `full-size-kana`
2. Support for grapheme based uppercasing, lowercasing, and
capitalization. These are all done per-code point right now.
3. Support for the language-specific `SpecialCasing.txt` cases for case
mapping such as the ones for Irish and Turkish.

This reverts the Rust edition updates to these three traits as well as
incorporates https://phabricator.services.mozilla.com/D117887. The
purpose of this change is to reduce the diff with upstream stylo.
Finally, formatting is disabled for these crates as well.
This deviates from css2, but it's mandated by css-align, and matches
what other browsers do when no margin is 'auto'.
When some margin is 'auto', this should keep the proper round-tripping
behavior that Gecko and WebKit lack, and Blink recently adopted.
This adds support for table rows, columns, rowgroups and colgroups.
There are few additions here:
1. The createion of fragments, which allows script queries and hit
testing to work properly. These fragments are empty as all cells are
still direct descendants of the table fragment.
2. Properly handling size information from tracks and track groups as
well as frustrating rules about reordering rowgroups.
3. Painting a background seemlessly across track groups and groups. This
is a thing that isn't done in legacy layout (nor WebKit)!

This is part of the preparation for splitting stylo into a separate
crate. We have made various changes to selectors includings:
1. Bumping the rust edition
2. Fixing typos and updating links
In addition to reverting those changes, this PR pulls in some changes to
selectors we seem to have missed in the process of updates.
Ubuntu 20.04 does not have libudev-dev causing build
failure when compiling libudev-sys, which is in-turn
needed by gilrs-core. Similarly, nix build also needs
the udev C library.
On Ubuntu 22.04, we don't see the build failures since
the build dependency 'libgstreamer-plugins-base-1.0-dev'
transitively pulls in libudev-dev.
Fixes#31373

* ci: Switch to version 4 of GitHub artifact actions
This switches to version 4 of the GitHub artifact actions, which
requires producing a single artifact per job and adding merge steps. In
addition, the names of artifacts are standardized:
- Build: <profile>-binary-<platform>
- Full WPT results (only on failure): wpt-full-logs-<platform>-<layout>
- Filtered WPT results (only on failure): wpt-filtered-logs-<platform>-<layout>
* Delete merged build timings and combine with Result job
* Always archives logs even after test failures
* Correct the name of the log files for WPT import
