layout: Force reflow in the sequential fallback of block format context
When reflowing a block format context during the inorder traversal,
propagate restyle damage manually to its children since they were
already reflowed. Also, test the border box to see if it can fit into
floats according to CSS 2.1 § 9.5.

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.
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.

style: Do not immediately convert absolute specified lengths
<!-- Please describe your changes on the following line: -->
This PR aims to solve issue #15729. I tried to follow the recommendations there as much as possible.
This is my first attempt at contributing to Servo, so this will probably need a lot of input, although I'm eager to make it as polished as possible.
- The base inaccuracy issue seems solved, as can be easily verified with the `console.log` based example in the issue.
- Very basic unit tests were added.
I have doubts mainly about the right way to represent these new enum variants for the various length units:
1. With new enum variants in `NoCalcLength` *and* newtypes (current solution)
2. With a `NoCalcLength::Absolute` variant that contains a new `AbsoluteLength` enum, but without newtypes
3. Same as solution 2 but with newtypes
- I mostly cared about unit tests until now but will investigate other types of tests
- Tests to check the clamping
- Write a proper commit message
Thanks for your time and feedback :)

The NoCalcLength::Absolute variant has been rewritten to accommodate
other units than Au with the new AbsoluteLength enum. This avoids loss
of precision for some operations.
The conversion from floating point absolute lengths to integer
application unit values adopts the same clamping limits as Gecko.

This is the first step toward removing inherited clips in favor of
scroll roots for handling overflow and CSS clipping. This will allow us
to more easily handle elements that should not be clipped. While we are
still using inherited clips here, we now properly clip some types of
content that wasn't clipped before.
