Reset longhands of border-image to their initial value while parsing border shorthand
To do so, we need to declare the border-image longhands as part of border
shorthand and always reset them.

To do so, we need to declare the border-image longhands as part of border
shorthand and always reset them. This could fix couple stylo test failures.
See Gecko Bug 1357350 for the test update patches.
Spec link: https://drafts.csswg.org/css-backgrounds-3/#the-border-shorthands
Note that two unit tests have been fixed as well:
1. border_should_serialize_correctly
To verify the correctness of serialization of 'border' shorthand, we need
to reset 'border-image' as well.
2. same_longhands_should_serialize_correctly
Due to the same reason as above, since the 'border-image' is not reset,
the test expectation should be fixed.
If there are multiple prefixed/non-prefixed @keyframes with the same name;
* non-prefixed rule overrides earlier rules.
* prefixed rule overrides earlier prefixed rules.

This improves cache locality and reduces allocations during parsing.

but that shouldn't matter.
Fix namespaces of elements created in XML documents
Correctly implement following step of [Dom Document Spec](https://dom.spec.whatwg.org/#dom-document-createelement):
> Let namespace be the HTML namespace, if the context object is an HTML document or context object’s content type is "application/xhtml+xml", and null otherwise.
Note, this will make following test in `tests/wpt/web-platform-tests/dom/nodes/Document-constructor.html` to fail, so related .ini file added to mark it as such:
```
test(function() {
var doc = new Document();
var a = doc.createElement("a");
// In UTF-8: 0xC3 0xA4
a.href = "http://example.org/?\u00E4";
assert_equals(a.href, "http://example.org/?%C3%A4");
}, "new Document(): URL parsing")
```
I'm not very familiar with specs, but from quick look at it, I'm doubtfull that it is valid in the first place. This is an "application/xml" document, so I don't see why it should encode a.href. Firefox also fails that.

Instead of passing down a complex clipping region to each item, used
shared clipping to handle overflow:hidden and CSS clips. In addition to
being more efficient, this should also fix quite a few issues related
to absolutely positioned elements.
One existing reftest is slightly modified to avoid tickling a quirk
with the way that WebRender rasterizes masks. We are working out how to
best express these combined masks with the API or need to. The change
does not affect the original subject of the reftest.
Fixes#13109.
Fixes#10151.
Fixes#7575.
Fixes#8074.
Fixes#8780.
Fix various issues with overflow clipping
When dealing absolutely positioned items, we should use clip of our
containing block, even if our containing block doesn't itself establish
a new overflow clip. Additionally, we need to properly handle
assigning scroll root ids to fragments of inline elements.
We add a test for this behavior.

This version enables [struct field reordering][1] which brings the size
of the types for specified values of some CSS properties under the threshold
such that they shouldn’t be boxed anymore, making unit tests fail.
Simply unboxing them moves the test failure to Stylo’s unit tests,
since the stable compiler used in that case does not do field re-ordering.
Therefore, we manually reorder a couple fields to effectively bring this
optimization to older compilers for a few specific types.
