These changes allow using MallocSizeOf/`#[conditional_malloc_size_of]`
on WebIDL callback values, and then fix a grab bag of places in the
script crate that previously ignored those values. There are also some
commits removing ignored fields that involved Arc/Rc that are not WebIDL
callbacks, since they are now easier to support with the
`#[conditional_malloc_size_of]` attribute.
Testing: Manual testing on about:memory for servo.org.

According to dependabot/dependabot-core#4364, dependabot now supports
excluding certain directories from upgrade scanning. This change adds
two problematic directories to the exclusion list.

Building on the preference observer work from #38649, we now
automatically install an observer when multiprocess mode is enabled.
This observer notifies the constellation of updated preferences, which
in turn notifies each content process so the changes will be reflected
into script/layout as expected. There's a unit test that verifies this
works correctly by checking a preference-gated WebIDL property before
and after the preference is toggled.
Testing: New unit test added.
Fixes: #35966
Depends on #38649.

Fix a large number of backend issues that were masking everything else.
There probably is still more, but it'll take more integration/unit
testing to find it.

`DevtoolsInstance::find_network_event_actor` silently creates a new
actor if there is not one already known for a given ID. This is
confusing; this PR separates logic for handling network requests (create
a new actor) and network responses (retrieve an existing actor).

Add an off-by-default allocator mode that tracks all live allocations
with sizes and associated stack traces. We also track if each allocation
is visited as part of a measuring heap usage in `about:memory`, allowing
us to report on allocations that are not tracked yet. Right now the list
of untracked allocations is dumped to stdout; I have a python script
coming in a separate PR which makes it easier to perform analysis on the
massive output.
Testing: Manually tested with `./mach build -d --features
servo_allocator/allocation-tracking` and visiting about:memory.

This change adds font variation support for macOS. The main bulk of the
change is reading the default, min, and max values for each variation
axis from the font and instantiating a new CoreText font with the
appropriate values.
In addition, fonts with variations are now properly cached in the
CoreText font cache.
Testing: There are no tests for this change as we do not run WPT tests
for
macOS and font variations are currently turned off by default.
Eventually,
when the feature is turned on there will be test for it. These changes
are just laying the groundwork for the full implementation.

`ComputedValuesExt::preferred_aspect_ratio()` was getting the natural
aspect ratio expressed logically as inline over block, but then it was
mixing it with the value of the `aspect-ratio` CSS property, which is
expressed physically as width over height.
Therefore, this changes `ComputedValuesExt::preferred_aspect_ratio()` to
expect the physical natural ratio, and then it takes care to convert the
resulting ratio logically.
Testing: Unneeded. This has no effect in practice because we don't
support `writing-mode` yet.

# Objective
Ensure that functionality which uses the raw font data (such as
rendering text to canvas) works correctly on macOS when the specified
font is a system font that lives in an OpenType Collection (`.ttc`)
file.
## Changes made
- The `read_data_from_file` in each backend now returns a `index: u32`
in addition to `data: Vec<u8>`
- The `data` field on the `Font` type has been renamed to `raw` and the
`data` method on the `Font` type has been renamed to `raw_font`. This
allows the index to be cached as computing is moderately expensive on
macOS (on the order of 100 microseconds).
- Both of the above now store/return a `struct RawFont` instead of a
`FontData` where `RawFont` is defined as `struct RawFont { data:
FontData, index: u32 }`.
- The users of the `data` method have been updated to use the cached
index from `data` rather than calling `.index()` each time.

Motivation:
Using our GenericChannel abstraction allows us to optimize IPC in
single-process mode to just use cross-beam channel.
To keep the diff low, and get early feedback, this PR only tackles a
single channel, but the intention is to port all ipc channels to the
generic channel, which allows us to skip serializing and deserializing
messages in single process mode.
Based on:
- https://github.com/servo/servo/pull/38638
- https://github.com/servo/servo/pull/38636
Testing: Covered by existing tests

`uv` logs a warning if the pyproject.toml does not contain a project
table.
There is not really much point in adding the table, but no downsides
either,
so lets just add the table to make `uv` happy.

Based on
[spec](https://w3c.github.io/webdriver/#dfn-extract-an-action-sequence),
`TickActions` should be a list. Previously we used Hashmap, which when
iterated has arbitrary order. This causes some tests to be unstable
previously (see the linked issue).
Testing:
`./webdriver/tests/classic/perform_actions/{pointer_contextmenu,
pointer_modifier_click}.py` consistently pass now.

Fix build failures when building without default features.
Testing: This was manually tested, but this PR does not add automated
tests of `--no-default-features` to CI.

After #38748, `WebDriverJSValue` is almost same as `JSValue`. Now we
turn "potentially merge into one in the future" into reality. The only
thing we should be cautious is to properly serialize `WebFrame`,
`WebWindow`, `WebElement` for WebDriver.
Testing: No regression. Some error is fixed previously by #38709 which
didn't update test :)
Binary size reduced by 134KB.

This change adds support for variable fonts via the
[`font-variation-settings`](https://developer.mozilla.org/en-US/docs/Web/CSS/font-variation-settings)
property.
There are three areas where we need to set the variation values:
* Webrender (`compositor.rs`), for drawing the glyphs
* Harfbuzz (`shaper.rs`), for most shaping tasks
* PlatformFont (`fonts/platform/`), for horizontal advances and kerning
For now, freetype is the only platform shaper that supports variable
fonts. I can't easily test the fonts with non-freetype shapers. Thats
why variable fonts are behind the `layout_variable_fonts_enabled` pref,
which is disabled by default.

This change fix this bugs: modify stylesheet of shadow tree does not
take effect if there is no other Dom change within the shadow tree
happens.
Fixes: This change fix some bugs reported by this issue #38211.
Testing: This fixes some subtests in
`/css/cssom/CSSStyleSheet-constructable.html` and
`/css/cssom/CSSStyleSheet-constructable-disallow-import.tentative.html`,
and make some subtest failed in
`/css/cssom/CSSStyleSheet-constructable-baseURL.html`, because the
`BaseUrl` is not yet supported for `CSSStylesheet`.

This will make it easier in a followup to include the normalized font
variations in the return value. This also make
`PlatformFont::ensure_h_kern_subtable` work on the instance instead of
being a struct method. Finally, all `PlatformFont` methods are combined
into a single impl block.
Testing: This should not change behavior and is thus covered by existing
tests.

This cleanup makes the interface a bit simpler and prevents problems
where the pseudo-element information is not passed by accident.
Testing: This should not change behavior, so is covered by existing
tests.

This shows up sometimes in code reviews, so it makes sense that tidy
enforces it. `rustfmt` supports this via comment normalization, but it
does many other things and is still an unstable feature (with bugs).
Testing: There are new tidy tests for this change.

Reimplementation of: #35931
For a `FragmentTree` we define a scrollable overflow calculation that
includes the overflow all of it's children `Fragments`. In practice we
are using this calculation for scrolling area of the viewport and
defining the root scroll frames. However, since uncontained fixed
positioned element is located outside of the document and should not be
scrolled, and therefore it would make no sense to include them in the
calculation of its scrollable overflow as well.
Testing: New and existing WPT tests

Replaces a big match statement with a call to `unicode_script`'s
`Script::short_name` method which has the same big match statement. We
special case `Script::Unknown` because the `short_name` method returns
empty string for that variant, but harfbuzz represents it with `Zzzz`.
EDIT: `Zzzz` seems to be in the spec so I've sent a PR to
`unicode_script` to use it:
https://github.com/unicode-rs/unicode-script/pull/23
EDIT: And https://github.com/unicode-rs/unicode-script/pull/24 which
would allow us to remove this method entirely.

This is part of introducing the Ruff rule [flake8-annotations
(ANN)](https://docs.astral.sh/ruff/rules/#flake8-annotations-ann) into
the script_bindings folder.
Since `codegen.py` has 10k lines of code, the strategy is to introduce
the rule first while ignoring the `ANN` Ruff rule for `codegen.py`. We
will then gradually add type annotations slice by slice to ensure no new
errors occur outside of `ANN`.
Testing: `./mach test-wpt webidl`

Since we don't enable the preference as part of
`--enable-experimental-web-platform-features` yet, we don't run any
automated tests for the AbortController feature. This change means that
we at least explicitly test the interface.
Testing: Just enabling new tests.

This only covers the global event handlers for now, while I figure out

WindowEventHandlers, but not sure where the others coming from.

Vendors the [blink perf
tests](https://chromium.googlesource.com/chromium/src/+/HEAD/third_party/blink/perf_tests/).
These perf tests are useful to evaluate the performance of servo.
The license that governs the perf tests is included in the folder.
Running benchmark cases automatically is left to future work.
The update.py script is taken from mozjs and slightly adapted, so we can
easily filter
(and patch if this should be necessary in the future.
Testing: This PR just adds the perf_tests, but does not use or modify
them in any way.
