Closes#18458.
Matches other browsers in test-cases like:
<div id="t" style="border-top-left-radius: 5px 5px"></div>
<script>alert(t.style.borderTopLeftRadius)</script>
(I think it'd be nicer to preserve the original value completely, but not going
to complain given we already do this for all sorts of Rect<T>s and such, and
this is much easier).
Before we did not properly descend intro truncated fragments when
collecting stacking contexts. This change makes sure that we descend
properly
Fixes#18254.
Fixes#17072.
Sending scroll positions to Webender is way too flaky to run the
position:sticky tests at this time. We need to disable them for now, so
that other Servo work can continue.

Add support for position:sticky
This leverages the position:sticky support in WebRender to bring basic
support for position:sticky in Servo. There are still some issues with
nested sticky flows as well as a few other corner cases. Tests are
imported from WPT and can be removed once we update to the latest
version.

Reduce usage of fmt in serialization and error reporting
`format!` and `write!` create a somewhat-heavyweight `Formatting` struct and use dynamic dispatch to call into impls of `Dispaly` and related traits. The former also allocates an intermediate string that is sometimes unnecessary.
I started looking into this from https://bugzilla.mozilla.org/show_bug.cgi?id=1355599, but I expect the impact there will be small to insignificant. It might be a slightly less so on parsing (error reporting).

Fix the long-standing bug where items that are positioned and have
overflow:scroll or overflow:auto automatically create stacking
contexts. In order to do this we need to fix another bug where display
list sorting can put a Clip or ScrollFrame definition after the first
time it is used in a display list.
Improve containing block creation for position:absolute flows
Instead of only promoting flows with positioned fragments to containing
blocks, also do this for flows which have the transform, perspective or
filter properties set. This is what the spec requires and also fixes
some failing tests. It will allow us to stop creating stacking contexts
for overflow:hidden and overflow:scroll flows.
Fixes#18091.

These tests assumed that foo-á would create a HTMLUnknownElement; however,
foo-á is a valid custom element name; therefore, according to the spec, a
HTMLElement instace is created instead. I changed the name to fooá so a
HTMLUnknownElement is created as the test expects.

In order to properly handle CSS clipping, we need to keep track of what
the different kinds of clips that we have. On one hand, clipping due to
overflow rules should respect the containing block hierarchy, while CSS
clipping should respect the flow tree hierarchy. In order to represent
the complexity of items that are scrolled via one clip/scroll frame and
clipped by another we keep track of that status with a
ClipAndScrollInfo.
