The Linux kernel imposes a 15-byte limit on thread names[1]. This means
information that does not fit in this limit, e.g., the pipeline ID of
layout and script threads, is lost in a debugger and profiler (see the
first column of the table below).
This commit shortens the thread names used in Servo to maximize the
amount of information conveyed. It also rectifies some inconsistencies
in the names.

Fix missing canvas text on UWP
This addresses the missing fonts under UWP by updating font-kit and assorted dependencies that all depend on older incompatible versions of freetype. This also works around #27492 by using a fork of webrender that cherry-picks required dependency updates without bringing in the commit that exposes an ANGLE crash.

- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix#27515
- [x] These changes do not require tests because no UWP tests.
It's not possible anymore, in the presence of min() / max(), to split a
<length-percentage> value into a <length> and a <percentage> component.
Tweak word_spacing to do what Gecko does (resolving it in advance).
Update a bunch of stuff to syn 1
This updates a lot of our crates to syn 1. Not all of them, but syn 1 was already in tree so it doesn't matter much either way.

<!-- Reviewable:end -->
This crate takes about 40 seconds to build of a fast desktop,
and was used in exactly one place. Additionally, that use was previously
accidentally disabled (a553964123)
and we only noticed more than a year later when the build broke
(d1efad6763).
There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.
