This fixes#12937 where keypresses arrive in a one-off fashion, effectively delaying each keystroke. This PR is based heavily on @codec-abc's https://github.com/servo/servo/pull/16193 PR, with some further fixes and cleanup. From the original PR comments:
> There are 2 types of events associated with keyboard: Key event (up or down) and Character Input.
>
> * A character is not necessary created one a key is pressed (like the home key).
> * A character may be created only using a combination of several key. For example, using a Qwerty International layout you have to type ` then e to get é. The first key press on ` will create no character.
> * In servo, we currently merge the 2 events together, meaning that we store a Character Input event in a field to fire a single event later on when we get a Key event.
>
> The order of events seems to be system dependent. For example, let's say that we type the A key on a Qwerty Layout. In Linux and MacOs we will get this:
>
> * Character Input for character A
> * Key down event with virtual key code of the key A
> * Key up event with virtual key code of the key A
>
> while in Windows we get:
>
> * Key down event with virtual key code of the key A
> * Character Input for character A
> * Key up event with virtual key code of the key A
>
> It seems that glutin make no attempt to reorder the event to make the order independent of the Operating System. I think it would be easier for Servo if it were handled by the library.
This fix is a stopgap for the current state of glutin. We may want to look into a deeper fix in the future. For now, this is hopefully adequate solution until a more permanent one can be found.
This is the last remaining issue for the Windows nightly blockers meta-issue https://github.com/servo/servo/issues/12125

I wanted to add an environmental variable to disable the style sharing
cache for gecko, but the current pattern involves lazy_static!, which
involves an atomic operation on lookup, which is a bit hot to do each
time we try to share styles. This makes that work happen once per
process.

scrollbars.css is the only sheet which is parsed as author level, but later
added as agent level in [1]. Add a new enum value so that it can be parsed
as author level in gecko (nsCSSParser::AgentRulesEnabled() will exclude it),
but servo can recognize it as agent level sheet when the sheet is created.
Delete UserRulesEnabled() because no one uses it.

AnimationValue::mGecko and AnimationValue::mServo are mutually
exclusive, so we have to make sure mGecko.IsNull() returns reasonable
value, or we will got assertions. Hence, we should initialize it during
constructing StyleAnimationValue from Servo side.

<!-- 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.

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.
