[@scope] Implement scoped declarations

This CL allows declarations to appear directly within an @scope
rule, e.g.:

@scope (.foo) {
color: green;
}

Such declarations match the scoping root with zero specificity, i.e.
as if wrapped in a :where(:scope) rule.

Using declarations directly is already possible when @scope
is a "nested group rule" [1] (i.e. nested within a style rule).
This capability is now extended to non-nested @scope rules as well [2].

part 6) Add missing tests to <to-javascript-parent-initiated-child-csp.html>.

Those tests cover all injection sinks mentioned at [1]. There could be
other injection sinks accepting javascript: URLs but I'm not aware of
such.

Tests for when the parent and child differ and both have a CSP will be
added in a separate patch.

[Sanitizer] Update tests to match current spec draft.

This adapts WPT tests to the current spec draft.

• sanitizer-secure-context + sanitizer-insecure-context are obsolete.
• sanitizer-query-config is superseded by sanitizer-config.

The other tests mainly adapt the API (e.g. getConfiguration() => get()).

Only skip non-leading item-less container fragments.

crrev.com/c/6022897 added code to skip over item-less container
fragments when painting an inline, as an attempt to map FragmentData
indices in a LayoutInline to the correct container fragment FragmentData
indices. However, in order to get this correct, we cannot skip leading
item-less container fragments, as InlineCursor has already taken those
into account.

Reland "webnn: implement reverse operator"

This is a reland of commit 0459ac1a9b94c1dd3e11410f7fb74f0a8e2ddeaf

The previous CL got reverted because another CL[1] changed the function
name buildGraphAndCompute to buildAndExecuteGraph in WPT. This CL
fixes the name.

[1] https://chromium-review.googlesource.com/c/chromium/src/+/5556220

Original change's description:

webnn: implement reverse operator

This CL adds IDL and mojo definition of reverse operator according to
the spec issue [1] and implements it on DirectML backend.
