Update the API, `nspectorUtils.getCSSStyleRules`. Add one extra
argument so the user can choose whether we should return the starting
style, for a given element, at this moment.

This fixes a regression with :has() on the test-case of bug 1480477 (but
we should still aim to make that faster).
While at it, avoid synchronization in some really hot paths, and add
tests.

This doesn't yet expose it to a11y but that will be done by the a11y
folks, since this blocks some of the a11y interop test-cases.
Modify the tests to not hit the network, and make -moz-alt-content not
exposed to content (we only need it for UA stylesheets).

We introduce this rule and parse it in this patch. Also, fix some wpt
expectations for ERROR.
We will introduce CSSStartingStyleRule in the following patch, and test
it there.

The event is emitted when a property is registered via `CSS.registerProperty`.
This will be used by DevTools so we can update the Rules view when a property
is registered.

Parsing is disabled by the layout.css.margin-rules.enabled pref.
This isn't currently testable beyond a crashtest because the DOM interface for
margin rules isn't implemented yet.

Call to CSS.registerProperty may result in rendering changes compared
to when variables were interpreted as unregistered custom properties.
Ensure we recascade style for the whole document tree.
This was already covered by WPTs but add a more direct check for
paint and reflow.

Things like @font-face / @font-pallete-values etc don't look into those
stylesheets.
This prevents bugs in invalidation like bug 1854742 from triggering on
shadow root style changes like when changing AdoptedStyleSheets and so
on.
