We don't need this for Gecko, and it's hard to implement in that case because
there's nowhere obvious to put it (we don't plan to create TSDs for non-dirty
nodes, and non-dirty nodes can have dirty children which require the
children_to_process atomic). There are various solutions here, but punting is
the easiest.
We'll need to rethink this if/when we need to do a bottom-up traversal for
Gecko.

Use `repr()` to get a Python string literal (whose character escaping
is compatible enough with Rust’s) and `[1:-1]` to remove the single quotes.

Start simplifying FFI ownership sugar
This is step one of a series of changes planned to make the ownership sugar easier to use. This was blocked on #13038
*very* unsure about second commit. Don't like the thought of accepting types with destructors over FFI. Probably will revert it. Leaving it in for now in case you have some insight.
Eventually at least for the borrowed stuff I want to use T directly (because the crates are merged now), instead of the fake void types. Perhaps for the others too. I might include those changes in this PR -- was originally planning to but I realized that these steps could be split out.
Tentative plan for `Owned` (assuming it's not removed) is to have `Owned<T> <-> Box<T>` (same `T`, no "FFI type") conversions. We will only use ownership wrapper types for things with destructors, and try to keep the conversion simple. I'm envisioning a couple methods for arc/strong and a few more for box/owned. We may need to introduce new wrapper types for gecko-side managed objects (`RefPtr<T>`, `UniquePtr<T>`) but that should be all the wrapper types we have in the ownership sugar.
This PR relies on the guarantee that `Option<&T>` and `Option<Box<T>>` are pointer-sized via the `NonZero` optimization. I am now less unconvinced that this is a good idea 😉.

Add to_css_single_value for serializing a single PropertyDeclarationBlock
(fixes#13423)
r? @birtles
This needs to take the name of the property in question as input so that it can figure out which shorthand to serialize to (if any), since some props are part of multiple shorthands (and you need a way to distinguish between the lone value and the shorthand). I can tweak this to accept an `Option<Shorthand>` in case you only want to pass in the property name for shorthands.
In case you don't want to handle shorthands at all, we probably don't need this method at all, since you can just assert that there's a single field and serialize that.
Also, is `!important` involved here?

The cache is never effective in this case since a style attribute
adds to the set of applicable declarations.
This also avoid avoids the cache giving out-dated (incorrect) results
when `PropertyDeclarationBlock` becomes mutable in a later commit.
This is sufficient for now since CSSOM is only implemented for
`Element.style`. When StyleRule mutation is added,
some additional mechanism (such as evicting the cache) will be needed.

It's not possible to implement a Ref::map equivalent method on AtomicRefCell
while having AtomicRefCell implemented on top of RwArc. We could potentially
reimplement AtomicRefCell to be more like RefCell and add a Ref::map equivalent
method, but I (and pcwalton) think we should try just cloning a few extra
Arcs at these callsites instead.

Implement `word-break: keep-all` (#9673)
<!-- Please describe your changes on the following line: -->
Implement the `keep-all` value for the `word-break` property, as specified in [CSS](https://drafts.csswg.org/css-text-3/#word-break-property).
The relevant CSSWG tests (in `tests/wpt/css-tests/css-text-3_dev/html/word-break-keep-all-*.htm`) do not currently pass. As far as I can tell, this is because the tests use some JavaScript code that is not working properly. (But then, it seems that most tests in this directory are failing at the moment. I'm not sure what can be done here for now.)
