Share specified URLs with Gecko
This makes use of our Arc offset machinery to allow Gecko to store Arc<String> values and ensure there are used appropriately.

ScrollRoot is an ever increasingly inaccurate name for this thing and
WebRender consistently uses ClipScrollNode nowadays. Stick with the
WebRender terminology to be consistent.
Fix the test count in the WPT formatter
This was broken by a change in the test harness.

Measure ImageValue objects.
We have about 11,500 of these when loading gmail in a Stylo-enabled build, from
SpecifiedUrls; the objects themselves account for about 1.3 MiB of memory, and
the strings within them about 2.9 MiB.
We also have a very small number of them on the Gecko side.

These are the necessary servo changes for https://bugzilla.mozilla.org/show_bug.cgi?id=1387594 .
I'm also re-importing the generated Gecko bindings from my object directory:
- servo/components/style/gecko/generated/structs_debug.rs
- servo/components/style/gecko/generated/structs_release.rs
But the number of changes to those files surprises me.

More codesize reductions for generated code
Bloaty says this shaves off another 20kb from style::properties-based functions. The more limited Debug implementations enable sharing the property name strings between more functions, which saves on code size in the end.

Use exhaustive match for cloning keyword value by default for property using enum class
rather than casting them to `u8` then do inexhaustive match.
I don't see why we couldn't do this.

style: Don't cache styles that got a cache hit on the second pass.
This avoids doing wasted work, at least in the recascade case, and pretty likely
in the other as well.

Rule cache
<!-- Please describe your changes on the following line: -->
This adds a TLS-based cache reset styles structs keyed off rule nodes. Reviewed in https://bugzilla.mozilla.org/show_bug.cgi?id=1367635 by me and Emilio.

Measure PropertyDeclaration more thoroughly.
This patch replaces the handwritten MallocSizeOf implementation for
PropertyDeclaration with a derived one, which gives much more thorough
measurement.
This requires (a) deriving MallocSizeOf for a *lot* of additional types (most
of which already have `derive(HeapSizeOf)` in Servo builds), and (b)
implementing MallocSizeOf for a few more types in the `malloc_size_of` crate.
These changes would significantly improve the reporting coverage for gmail if
it weren't for the fact that SpecifiedUrl isn't measured due to a lack of
clarity about its fields; that can be fixed as a follow-up once bug 1397971 has
landed.
