The lack of specificity for script intro type has lead the debugger to need
to make use of 'source.introductionType' and 'source.element' in order to
determine whether a given script was injected, or inline or fetched, which
is entirely unnecessary of the loader itself clearly tells us what type
of script we are working with. It also allows us to cleanly handle the case
of XUL, which previously was "scriptElement" but has no ".element" passed
in, so we were unable to know whether a given source was inline or not.

We were getting duplicated nsIScriptError in the Browser Toolbox console and the Browser Console
when the multiprocess pref is enabled, because error from content processes are forwarded to
the main process.
The previous patch of this queue added a isForwardedFromContentProcess flag to nsIScriptError,
that we use in this patch to _not_ handle forwarded messages in multiprocess browser console
and browser toolbox console.

According to SVG Accessibility API Mappings, an SVG element which has title or desc element must be exposed.
https://w3c.github.io/svg-aam/#include_elements
Previously, we didn't expose <g> elements at all even if they had a title/desc, and we unconditionally exposed some other SVG elements even when they didn't.
This removes the Dev Tools A11y Panel code which explicitly allowed unlabelled descendants of role="img" <svg> elements, since we don't create descendants if they don't have a label now anyway.
The associated tests had to be tweaked as well, since now we don't create unlabelled descendants.
Original patch by Takeshi Kurosawa.

OuterWindow ID is deprecated in a Fission world and we should rather use Browsing Context ID.
The outer window ID will change when navigating to another origin, loaded in a distinct process,
whereas Browsing Context ID will stay the same.

Before this patch, we were not trying to cleanup anything when the process
was known to be in process of destruction. We assumed that everything would
be cleaned up anyway.
But mochitest is actually asserting that nothing is leaked on process shutdown,
and we are easily leaking many thing when not destroying the target actor!

This should help better classify DAMP errors as this was picked up by TreeHerder log parser,
while not breaking DAMP.

In order to retrieve the list of impacted element for a given CSS warning,
we are evaluating a document.querySelector expression,
using the cssSelector we get from the error itself.
But if the warning message comes from an iframe, we are not retrieving the
impacted elements, only items from the top-level document.
By storing the target actor id a message is emitted from directly in the message
itself, we can retrieve the target front, and use it to do the evaluation against
the right target.
This is not enough though, as non-remote frame don't have a dedicated target,
and we'll be back at square one, using the top-level document to do the evaluation.
In order to fix that, we're passing the innerWindowID to the evaluateJSAsync method,
so it can be used on the server to retrieve the window instance we need.
A test is added to ensure this feature works as expected for iframes, and it
passes with or without fission enabled.

This prevents showing e.g. ::cue pseudo-elements for elements that are
not videos, and such.
This is useful on its own, but it's going to be even more useful because
I'm making some rules in the UA sheets less specific in the blocking
bugs.
For example, after my patches, the number of expected rules in
test_styles-applied was 24 (instead of 9 with this patch). That's just
too much noise.

In order to test its parsing and serialization, we expose it but protect
it behind a pref.
Besides, I would like to drop layout.css.aspect-ratio-number.enabled in
the next patch because the spec has been updated. It seems we don't have
to keep this pref and we should always use Number.
