This change adds a very simple implementation of `border-collapse` for
tables. No harmonization or merging is done at all for borders. Instead,
the largest border for every continuous border sets the size. Instead of
merging different border styles, they are squashed to half size -- which
isn't great, but ensures appropriate positioning.

For a long time, `gfx_traits` has held a lot of things unrelated to graphics
and also unrelated to the `gfx` crate (which is mostly about fonts).
This is a cleanup which does a few things:
1. Move non `gfx` crate things out of `gfx_traits`. This is important in
order to prevent dependency cycles with a different integration between
layout, script, and fonts.
2. Rename the `msg` crate to `base`. It didn't really contain anything
to do with messages and instead mostly holds ids, which are used
across many different crates in Servo. This new crate will hold the
*rare* data types that are widely used.
Details:
- All BackgroundHangMonitor-related things from base to a new
`background_hang_monitor_api` crate.
- Moved `TraversalDirection` to `script_traits`
- Moved `Epoch`-related things from `gfx_traits` to `base`.
- Moved `PrintTree` to base. This should be widely useful in Servo.
- Moved `WebrenderApi` from `base` to `webrender_traits` and renamed it
to `WebRenderFontApi`.
Color emoji support with "Noto Color Emoji" requires two things:
1. Support for bitmap fonts in the FreeType backend. This requires
specially handling bitmap fonts which have different characteristics
in the FreeType API (such as requiring metrics scaling). This support
is generally ported from Gecko's implementation.
2. When a character is an emoji it "Noto Color Emoji" needs to be in the
fallback list. Ensure that this is high on the list -- this will be
improved in a later PR.

* feat: Support font-relative `ch` and `ic` units
After #31966, which made it possible for the first time to resolve
font-relative CSS units, this change adds support for the `ch` and
`ic` units.
One difference with the `ex` unit that was added in that PR is that
these units must reflect the advance width of a character (the zero
digit in the case of `ch`, and the CJK water radical for `ic`) as it
would be rendered by the current font group. This means that the size
of these units don't only depend on the first available font, in the
case where that font does not contain a glyph for that character.
This is implemented by adding the advance width for these two
characters as optional fields of `FontMetrics`, so the advance width
computation happens in advance. Then, when the font metrics are
queried as part of unit resolution, the font group is searched for the
first font containing that character.
This change only implements support for these units in upright
typesetting modes, since Servo does not yet have support for vertical
writing modes. This means that many of the WPT tests that test for the
behavior of these units with vertical writing modes do not pass.
This change also makes a number of WPT tests pass, which relied on the
`ch` and `ic` units. It, however, also makes the test
`/css/css-text/white-space/text-wrap-balance-overflow-002.html` fail,
since it tests `text-wrap: balance`, which Servo does not yet
implement, and it was only previously passing by chance due to the
previous behavior of these units.
* Revert Python 3.10-related changes to wss
* Fix formatting
* Remove test expectation
There are a couple major changes here:
1. Support is added for the `weight`, `style`, `stretch` and
`unicode-range` declarations in `@font-face`.
2. Font matching in the font cache can return templates and
`FontGroupFamily` can own mulitple templates. This is due to needing
support for "composite fonts". These are `@font-face` declarations
that only differ in their `unicode-range` definition.
This fixes a lot of non-determinism in font selection especially when
dealing with pages that define "composite faces." A notable example of
such a page is servo.org, which now consistently displays the correct
web font.
One test starts to fail due to an uncovered bug, but this will be fixed
in a followup change.
Fixes#20686.

While <https://drafts.csswg.org/css-lists/#list-style-position-property> says:

All other browsers ensure that the first line of list item content is
the same block size as the marker. Doing this is complicated, but we can
ensure that the entire list item is at least as tall as the marker. This
should handle the majority of cases and we can make refinements later
for stranger situations, such as when the marker is very tall.

Bumps Stylo to servo/stylo#37
`white-space` is split into `white-space-collapse` and `text-wrap-mode`:
| white-space | white-space-collapse | text-wrap-mode |
| ----------- | -------------------- | -------------- |
| normal | collapse | wrap |
| nowrap | collapse | nowrap |
| pre-wrap | preserve | wrap |
| pre | preserve | nowrap |
| pre-line | preserve-breaks | wrap |
| - | preserve-breaks | nowrap |
Note this introduces a combination that wasn't previously possible,
but I think the existing logic can handle it well enough.
The old `allow_wrap()` is replaced by checking whether `text-wrap-mode`
is set to `wrap`.
The old `preserve_newlines()` is replaced by checking whether
`white-space-collapse` is *not* set to `collapse`.
The old `preserve_spaces()` is replaced by checking whether
`white-space-collapse` is set to `preserve`.

* Let legacy layout serialize shorthands in getComputedStyle
This ports #31277 (with the changes from #32066) into legacy layout.
Otherwise, turning white-space into a shorthand (#32146) would fail
some tests that expect the property to be serializable.
* Update text expecatations
Tables should always be at least as big as their min-content size, even
if we would expect a smaller size according to CSS sizing properties.
#31455 implemented it for in-flow tables participting in flow layout,
but a few cases remained. This patch addresses floated tables.
Previously, the "scroll to fragment" operation could scroll past the end
of the screen, because the scroll position was not clamped to viewport
boundaries. Correct this by using the `Window::scroll()` method which
handles this case.
In addition, ensure that `Window`'s `current_viewport` member is
initialized properly when it is created.
This change adds very basic support for `list-style-position`.
Currently, the marker does not do any kind of baseline alignment with
the rest
of the list item contents and it also doesn't force the list item to be
at least as tall as the marker.
This adds a few new failures:
- Four failures because markers do not ensure that list-items have at
least the same block size as they do:
- FAIL [expected PASS] /css/CSS2/lists/list-style-applies-to-012.xht
- FAIL [expected PASS] /css/CSS2/lists/list-style-applies-to-014.xht
- FAIL [expected PASS]
/css/CSS2/lists/list-style-type-applies-to-012.xht
- FAIL [expected PASS]
/css/CSS2/lists/list-style-type-applies-to-014.xht
- One failure because we don't yet support the `::marker`
pseudo-selector:
- FAIL [expected PASS]
/css/css-position/position-absolute-dynamic-list-marker.html
- One failure because we don't support the list item exception for the
line height quirk:
- FAIL [expected PASS] /quirks/line-height-in-list-item.tentative.html

This fixes several tests in
[wpt/user-timing](https://wpt.fyi/results/user-timing?label=master&product=chrome%5Bexperimental%5D&product=firefox%5Bexperimental%5D&product=safari%5Bexperimental%5D&product=servo&aligned)
by fixing some logic errors in how marks/measures are cleared (via
[`clearMarks`](https://developer.mozilla.org/en-US/docs/Web/API/Performance/clearMarks)
and
[`clearMeasures`](https://developer.mozilla.org/en-US/docs/Web/API/Performance/clearMeasures)).
There are two changes:
1. Fix the boolean logic in `clear_entries_by_name_and_type` so that,
when `clearMarks('foo')` or `clearMeasures('foo')` is called, the
presence of the entry name correctly filters based on existing entry
names.
2. Make the `entry_name` param a `DOMString` rather than an
`Option<DOMString>` since every API call has it as `Some` anyway, and
I'm not aware of any [Performance
APIs](https://developer.mozilla.org/en-US/docs/Web/API/Performance)
where you can clear all entries regardless of type. (This is not
strictly required for the fix, but I think it makes the code easier to
read.)
~~I also considered adding the expected WPT results using `mach
update-wpt`. But I'm not sure if you want these changes, since the
expectations are currently missing (i.e. `tests/wpt/meta/user-timing`
does not exist).~~ (_Update: added!_)
For the record, this PR fixes the following tests:
- `clearMarks.html.ini`
- `clearMeasures.html.ini`
- `clear_non_existent_mark.any.js.ini`
- `clear_non_existent_measure.any.js.ini`
- `clear_one_mark.any.js.ini`
- `clear_one_measure.any.js.ini`

I noticed in #32123 that there are two issues with the docs for updating
Web Platform Tests:
- `./mach update-wpt --sync` fails with an error (`Are you sure you
don't want a patch?`) because it expects a `--patch` arg.
- The `tests/wpt/meta-legacy-layout/` test results need to be updated
with a separate command.
This updates `tests/wpt/README.md` with more complete instructions.

A `TextRun` is composed of `TextRunSegment`s that are composed of
`GlyphRun`s.
`TextRun::glyph_run_is_preserved_newline` is indexing into the `TextRun`
text, but the `GlyphRun` indexes that it uses are relative to the
`TextRunSegment`
offset. Before the code was using the offset without incorporating the
`TextRunSegment` offset. This led to miscalculation of preserved newline
location while processing text content.

`<br>` elements are a bit "special" in the sense that they defer a
linebreak, but can also have `clear` applied to them. The `clear` that
they supply should be applie *after* the linebreak is processed. This
change adds special processing for this situation.
Fixes#15402.
The logic was to remove any collapsible white space preceded by other
white space. However, this should only happen if the preceding space
is also collapsible.
Also fixing the logic in ContentSizesComputation, which was wrong
but previously it didn't matter.
