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).

layout: Stop call normal block size assignment for flex container
No need to call the `assign_block_size_block_base()` method of normal block in flex.rs since it is implemented for CSS2.

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.

Unwrap function before calling IsConstructor
`IsConstructor` returns true for all wrappers that are callable. Wrapped
arrow functions are callable and thus `IsConstructor` will return true
if given one; however, if we unwrap the arrow function, `IsConstructor`
will return false. The latter is the correct behavior here.

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.
IsConstructor returns true for all wrappers that are callable. Wrapped
arrow functions are callable and thus IsConstructor will return true
if given one; however, if we unwrap the arrow function, IsConstructor
will return false. The latter is the correct behavior here.

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.
The previous instructions did not work because of how
resources/testharnessreport.js is actually a template. Update the instructions
to provide instructions for replacing that file.
