PR for [Gecko bug 1359658](https://bugzilla.mozilla.org/show_bug.cgi?id=1359658)
When an element has a display:none ancestor we don't traverse it during
restyle. However, at the end of restyling we expect the tree to be free
of dirty bits. We currently take special care to clear the regular
(non-animation) dirty bit on nodes in display:none subtrees in order to
preserve this invariant. This patch applies the same handling to the
animation-only dirty descendants bit.

If we append a child to a display:none element, and we use StyleNewChildren on
that parent, we should skip restyling the children.

It seems mod attr is not used for geckolib at all, and that is the only place where servo_url is still referenced for geckolib, so we can just remove it.

The current mechanism requires threading a lot of this state through a bunch of
callsites that are several layers of abstraction above the code that actually
uses this vector (which is only compiled for servo). Putting it in
CurrentElementInfo gets it nicely out of the way.

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.

This way we'll be able to take different paths for the sequential and parallel
traversals in some concrete cases.

Something I just noticed while re-reading that code is that we prevent sharing among siblings with different non-common attributes, even though we already have the infra to match those selectors:
```rust
if !match_same_not_common_style_affecting_attributes_rules(element,
candidate_element,
shared_context) {
miss!(NonCommonAttrRules)
}
```

Style no forced docs for the properties code and similar, but I ran out of time, and I think it's a nice improvement.
I'd appreciate a fast-ish turn-around time because this is pretty much prone to bitrot.

With this PR, the only remaining usage of UnsafeNode is the transition stuff, which is servo-only and probably going to be rewritten over the course of stylo. The parallel traversal is now fully typechecked and safe. \o/

This PR removes the `util` crate.

* Moved `opts`, `prefs` and `resource_files` into a new `config` crate.

The primary idea of this patch is to ditch the rigid enum of Previous/Current
styles, and replace it with a series of indicators for the various types of
work that needs to be performed (expanding snapshots, rematching, recascading,
and damage processing). This loses us a little bit of sanity checking (since
the up-to-date-ness of our style is no longer baked into the type system), but
gives us a lot more flexibility that we'll need going forward (especially when
we separate matching from cascading). We also eliminate get_styling_mode in
favor of a method on the traversal.
This patch does a few other things as ridealongs:
* Temporarily eliminates the handling for transfering ownership of styles to the
frame. We'll need this again at some point, but for now it's causing too much
complexity for a half-implemented feature.
* Ditches TRestyleDamage, which is no longer necessary post-crate-merge, and is
a constant source of compilation failures from either needing to be imported
or being unnecessarily imported (which varies between gecko and servo).
* Expands Snapshots for the traversal root, which was missing before.
* Fixes up the skip_root stuff to avoid visiting the skipped root.
* Unifies parallel traversal and avoids spawning for a single work item.
* Adds an explicit pre_traverse step do any pre-processing and determine whether
we need to traverse at all.

This builds on @emilio's rule tree work. The goal is to raise the boundary between rule node computation and property cascading higher up the callstack, so that the new traversal architecture can decide to do one but not the other.

This patch introduces infrastructure for the rule tree, and constructs it.
We don't use it yet, nor have good heuristics for GC'ing it, but this should not
happen anymore once we store the rule node reference in the node.
I haven't messed up with memory orders because I want to do a try run with it,
then mess with them.
