Summary:
This should make it easier to report errors, and also reduce codesize.
The reason this was so generic is that error reporting was unconditionally
enabled and was super-hot, but now that's no longer the case after bug 1452143,
so we can afford the virtual call in the "error reporting enabled" case.
This opens the possibility of simplifying a lot the error setup as well, though
this patch doesn't do it.
Test Plan: No behavior change, so no new tests.

Bug #: 1469957
Differential Revision: https://phabricator.services.mozilla.com/D1734
MozReview-Commit-ID: F3wTdhX9MB5
Atomic<bool> is implemented in terms of AtomicBase<uint32_t>, because that way
you don't need to depend on atomic 1-byte operations. That means that the rust
bindgen sees it as a u32, not a bool.
It's a bit concerning that the rust code seems to be doing an unsynchronized
read here, but given this is a RelaxedAtomic, that's probably ok.
This patch is meant to be squashed with the following two. This is an initial
strawman implementation that I wrote to unblock jwatt, cleanups and fixes
follow.
Note that this is style pretty much untested until jwatt's patches are ready,
since Gecko doesn't understand the angle at all, but I expect the fixes to be
minor.

Now that rustfmt is getting close to stable, and work on the style system has died down a bit, it seemed like an opportune time to auto-format the style crates.
The first commit disables import reordering, since tidy and rustfmt don't currently agree on the correct ordering. The second commit does a bunch of manual fixups such that the output of rustfmt passes tidy. The third commit runs rustfmt on the three aforementioned crate.
There are a few dozen warnings in the style crate about lines longer than 100 characters. It would be good to fix these, but I don't have time for that now.

… rather than the start location of the current construct. This likely places the error just *after* of the unexpected token whereas before would be best, but that’s likely a much bigger change.

It doesn't make much sense to store `font-weight` as separate enums, especially given that we would need to support (somehow) arbitrary font weight value when we implement CSS Fonts Level 4.
This PR refactors the `font-weight` a bit to make it store as `u16` directly.

Generally we use computed values for `@font-face` rule descriptors but that descriptor is a bit different than the others in gecko side. It accepts strings instead of unsigned integer(which is computed value of this property). So we had to use SpecifiedValue for that in here.

**NOTE** The alternative for me is just to duplicate the ToCss code, which is not bad and is less code changed! Don't know what others would think, though. Looking for feedback!
A future patch series has some values that should be separated by spaces. This
allows us to re-use the code for serialization, but the types do get a little
clunky. The separator is now indicated with an associated type.

This requires https://github.com/servo/rust-cssparser/pull/143 for the final commit. There's no better way to split that work up, unfortunately, and it's extremely easy to bitrot. I would appreciate if we could expedite reviewing this work.
This is the work necessary to enable https://bugzilla.mozilla.org/show_bug.cgi?id=1352669. It makes sense to merge it separately because it's so much effort to keep it up to date with the ongoing Stylo work.

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<_>`.

<!-- 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.
