When the computed restyle damage is empty, do not do a layout. Instead,
just rebuild the display list. In the future, even that can be omitted,
but that requires changes to the compositor.
These kind of relayouts commonly happen when the cursor is moving around
the page and no style rules cause changes to :hover.
Testing: This is covered existing WPT tests and should only have
performance
impacts. Unfortunately there are currently no performance tests.

This makes servo use less file descriptors for animated images and
avoids the crash described in
https://github.com/servo/servo/issues/36792.
Doing this also forces the end users to be more explicit about whether
they want to deal with all image frames or just the first one.
Previously, `Image::bytes` silently returned only the data for the first
frame. With this change there's now a `frames` method which returns an
iterator over all frames in the image.
Testing: No tests - this simply reduces the number of fds used. Servo
doesn't currently display animated gifs anyways.

This way, we don't always set the destination to Document (which is as
the spec is written today). Instead, we set it it in the load_data,
depending on which context we load it from.
Doing so allows us to set the `Destination::IFrame` for navigations in
iframes, enabling all frame-related CSP checks.
While we currently block iframes when `frame-src` or `child-src` is set,
their respective tests don't pass yet. That's because we don't yet
handle the cases
where we fire the correct `load` event.
Also update one WPT test to correctly fail, rather than erroring. That's
because it was using the wrong JS test variable.

This change adds a shadow-tree widget for `<input type=color>` elements.
It also involves some changes to the way layout interacts with the DOM,
because currently all `input` and `textarea` elements are rendered as
plain text and their descendants are ignored. This obviously doesn't
work for `<input type={color, date, range, etc}>`.
<details><summary>HTML used for the screenshot above</summary>
```html
<input type=color>
```
</details>
Testing: I doubt that this affects WPT tests, because the appearance and
behaviour of the widget is almost entirely unspecified.

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:

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.
