This is required to publish script_bindings, since all files used during
codegen need to be there.
It might also be possible to generate the bindings ahead of time and
vendor them in-tree, but this seems painful to setup from a CI
perspective.
Since there don't seem to be any other users in-tree we can just vendor
into the script-bindings directory.
`ply` is licensed under the BSD 3 clause, and WebIDL under MPL-2.0, with
the licenses available in our cargo package. Both tools won't end up in
`servo` since they are build-time dependencies, so I believe we don't
need to adjust the crate license, or configure `about.toml`.
Testing: Should be covered by existing tests. We don't test if this
allows vendored builds or published builds.
Fixes: Partial fix for #43145

Bumps Stylo to https://github.com/servo/stylo/pull/314
In particular, we would now get a compile error because we were setting
`layout.flexbox.enabled` and `layout.css.transition-behavior.enabled`,
even if Stylo removed at some point. So stop setting them.
Testing: Not needed, no behavior change

The implementation of `attr()` in Stylo is not complete, but this way we
can start testing for it.
Bumps Stylo to https://github.com/servo/stylo/pull/306
Testing: Various tests pass, also a few failures. No impact on users,
even with experimental features enabled.

This changes updates to the latest version of stylo which includes
vendor-prefixed properties such as `-moz-transform` and
`-webkit-transform`. This allows more web content to render properly.
Note: Unitless perspective is not supported as part of this yet, but
will be once https://phabricator.services.mozilla.com/D274128 is part
of our downstream version of Stylo.
Testing: There are tests for this change.
Fixes: #17635.

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 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`

Introduce type checking with Pyrefly in `components/script_bindings`
This commit adds Pyrefly-based type checking to the
`components/script_bindings` directory. The primary goal is to catch
type inconsistencies early and reduce the likelihood of unexpected
runtime errors.
This change affects the `webidl` component, as these script bindings are
responsible for connecting WebIDL specifications to the Rust codebase.
Testing: `./mach test-wpt webidl`

Renames the files to pythonic file names. Also replaces the bespoke
caching function with the functools caching function which is
functionally equivalent.

We were already not compiling it and not running tests on it by default.
So it's simpler to just completely remove it.
