Add mock SVGImageElement interface to fix TIMEOUT WPT tests
which are related to ImageBitmap (html/canvas/*).
https://svgwg.org/svg2-draft/embedded.html#InterfaceSVGImageElement
Rationality of this change to fire event "error" on any attempt to fetch
image resource on href attribute change to not block WPT tests
execution.
Some WPT tests use the legacy namespace attribute "xlink:href", so
support for it was added to source code.
https://svgwg.org/svg2-draft/linking.html#XLinkHrefAttribute
- setAttributeNS("http://www.w3.org/1999/xlink", 'xlink:href', src);

This change adds the simplest kind of incremental layout. When Servo
detects that all style changes only require a repaint, only run stacking
context tree and WebRender display list generation. This means that
these kind of restyles do not need a re-layout. Instead, the existing
box and fragment trees will be used and the styles of damaged nodes will
be updated in their box and fragment tree nodes.
This requires a new style repair DOM traversal for nodes that have had
their style damaged. In addition, careful accounting of all the places
where we store style must happen in order ot update those styles.
Testing: This is covered by existing WPT tests as it should not change
observable behavior.
We have created a test case which shows a 50% speedup when run
in Servo, even though there still a long way to go to match the speed
of other browsers:

Unfortunately while it now passes almost all cases in
`tests/wpt/tests/content-security-policy/script-src/nonce-enforce-blocked.html`,
the test in question doesn't pass yet as it requires all cases to be
correct. Here, we still miss the "check for duplicate attributes during
parsing". Since we don't have this information available yet from the
parser, skip this for now.

To be able to abort the update, extract the functionality into a
separate method. Otherwise, we don't run the `node.rev_version` at the
end, which according to the comment is probably important.
Not all `style-src` tests pass and I don't fully understand why yet, but
I presume it has to do with some special quirks of stylesheets that
other CSP checks don't have. All `style-src-attr-elem` tests pass
though.

The two significant changes here are 1) a commit that frees memory used
to perform memory reporting once the reporting is complete, 2) memory
reporting for the system font service. There are various other commits
that remove `#[ignore_malloc_size_of]` attributes for data that we are
now able to measure, but they do not significantly change our
measurements when testing servo.org.
Testing: Comparing the output of about:memory on servo.org.

As a follow-up to the recent introduction of `script.src`
as trusted sink, this PR refactors machinery to also
support `TrustedScript`. In doing so, all trusted sinks
in `HTMLScriptElement` are now covered.
Instead of calling the callbacks in `policy.createX`,
we now have a `TrustedType` enum that specifies which callback
to invoke. Unfortunately we still have the `USVString` vs
`DOMString` problem, which is why we need to `.map` twice
to retrieve the backing `String` and avoid two different
types.
Additionally, I saw that `script.text` should have called
the "String replace all" algorithm rather than setting the
child contents. So that's also now fixed.

This macro does not hide any complex or unsafe implementation details,
and, it's only used in two files (node.rs and element.rs). This patch
removes the macro, and move the implementation in place.
Moreover, the Element::rare_data_mut function in element.rs is called by
other functions, so the #[allow(dead_code)] annotation is removed. The
Node::rare_data_mut function in node.rs is not called anywhere, so it is
removed.
Testing: No test is needed for this cleaning up.

We now check the sink of script.src for trusted types. This is the first
attribute that we check, other sinks will be implemented in follow-up
changes.
The algorithms currently hardcode various parts. That's because I need
to refactor a couple of algorithms already present in TrustedTypePolicy.
They use callbacks at the moment, which made sense for their initial
use. However, for these new algorithms they don't work. Therefore, I
will align them with the specification by taking in an enum. However,
since that's a bigger refactoring, I left that out of this PR (which is
already quite big).
The other trusted types support (createScript and createHTML) will also
be implemented separately.

The `Constellation` previously held a `window_size` member, but this
assumes that all `WebView`s have the same size. This change removes that
assumption as well as making sure that all `WebView`s pass their size
and HiDIP scaling to the `Constellation` when they are created.
In addition
- `WindowSizeData` is renamed to `ViewportDetails`, as it was
holding more than just the size and it didn't necessarily correspond to
a "window." It's used for tracking viewport data, whether for an
`<iframe>` or the main `WebView` viewport.
- `ViewportDetails` is stored more consistently so that conceptually an
`<iframe>` can also have its own HiDPI scaling. This isn't something
we necessarily want, but it makes everything conceptually simpler.
The goal with this change is to work toward allowing per-`WebView` HiDPI
scaling and sizing. There are still some corresponding changes in the
compositor to make that happen, but they will in a subsequent change.
Testing: This is covered by existing tests. There should be no behavior
changes.

Among other things this adds a new `EmbedderMsg::ShowSelectElementMenu`
to tell the embedder to display a select popup at the given location.
This is a draft because some small style adjustments need to be made:
* the select element should always have the width of the largest option
* the border should be part of the shadow tree
Apart from that, it's mostly ready for review.

This fixes common crash related to slottables, currently present on wpt.fyi.
Previously, the traversal parent of `Text` nodes was incorrectly
assumed to always be the parent or shadow host. That caused crashes
inside stylo's bloom filter. Now the traversal parent is the slot
that the node is assigned to, if any, and the parent/shadow host otherwise.
The slottable data for Text/Element nodes is now stored in NodeRareData.
This is very cheap, because NodeRareData will already be instantiated
for assigned slottables anyways, because the containing_shadow_root
field will be set (since assigned slottables are always in a shadow
tree). This change is necessary because we need to hand out references
to the assigned slot to stylo and that is not possible to do (without
unsafe code) if we need to downcast the node first.
As a side effect, this reduces the size of `Text` from 256 to 232 bytes,
because the slottable data is no longer stored there.
