Fix#16165.
Also, it turns out that the CSSFontFaceRule IDL specified in the css-fonts spec is not web-compatible. Instead browsers implement a .style attribute like in CSSStyleRule: https://github.com/w3c/csswg-drafts/issues/825
This in turn requires preserving data about which descriptors were set or not (distinguishing unset from set to a value that happens to be the initial value), so this commit also makes every field `Option<_>`.

I implemented full parsing and serialization for the mask-repeat and background-repeat style properties. I think some more tests are required but I'm not what I'm missing. I'd appreciate some direction.
I also had to modify some layout code to get my changes to compile. As a result, background-repeat should work individually in both directions now too.

<!-- Please describe your changes on the following line: -->
Before this PR, every object reflected in CSSOM is in `Arc<RwLock<_>>` to enable safe (synchronized) mutable aliasing. Acquiring all these locks has significant cost during selector matching:
* https://bugzilla.mozilla.org/show_bug.cgi?id=1311469
* https://bugzilla.mozilla.org/show_bug.cgi?id=1335941
* https://bugzilla.mozilla.org/show_bug.cgi?id=1339703
This PR introduce a mechanism to protect many objects with the same `RwLock` that only needs to be acquired once.
In Stylo, there is one such lock per process (in a `lazy_static`), used for everything.
I non-Stylo Servo, I originally intended to have one such lock per document (for author-origin stylesheets, and one per process for user-agent and user sytlesheets since they’re shared across documents, and never mutated anyway). However I failed to have the same document-specific (or pipeline-specific) `Arc` reachable from both `Document` nodes and `LayoutThread`. Recursively following callers lead me to include this `Arc` in `UnprivilegedPipelineContent`, but that needs to be serializable. So there is a second process-wide lock.
This was previously #15998, closed accidentally.

Fixes font shorthand serialization so that it serializes to "" when non-default subproperties are defined. These subproperties are those defined in #15033.
Adds tests:
- font_should_serialize_to_empty_if_there_are_nondefault_subproperties
- font_should_serialize_all_available_properties
The second test was previously commented out and underwent some cleanup to make it run.

I think these properties are generally rare enough that they're not worth adding 8 bytes of memmove overhead on every PropertyDeclaration. There are a _lot_ of 24-byte properties though, so I think that's probably a good sustainable level.

Right now they don't, which means that we have four properties making PropertyDeclaration 16 bytes bigger than it should be.
I'm not sure if there's a better way to get these tests to run against stylo than to hoist them into the properties file, but I couldn't figure it out. This seems good enough.
