`ElementStyles` holds an optional list of values for each eager pseudo-element.
However, the type was declared as a slice instead of a fixed size array, so an
extra 8 bytes were being allocated to hold the size, even though it never
changes.
Moving the constant size into the type reduces `ElementStyles` and `ElementData`
by 8 bytes.

Before this change, the `ComputedStyle` struct that is part of permanent style
data per element holds 2 `StrongRuleNode`s (unvisited and visited) and 2
`Arc<ComputedValues>` (unvisited and visited).
Both rule nodes and the visited values don't actually need to be here. This
patch moves these 3 to new temporary storage in `CascadeInputs` on
`CurrentElementInfo` during the match and cascade process. Rule nodes are
pushed down inside the `ComputedValues` for later access after the cascade.
(Visited values were already available there.)
The permanent style data per element now has just the `Arc<ComputedValues>` for
itself and eager pseudo-elements (plus the `RestyleHint`).

In the patch after this, the existing `ComputedStyle` type is renamed and
repurposed as temporary storage of inputs for the cascade. To make it a bit
easier to follow what code is new, this patch starts by copying `ComputedStyle`
to context.rs without changes.

Remove target and data fields from parse_node_data
<!-- Please describe your changes on the following line: -->
`parse_node_data` does not need to store `data` and `target`, they can automatically be passed as parameters to the parser operation (`ParseOperation::CreatePI`) that we already create to be processed.
Also, this frees up `process_op` from depending on the sink's `parse_node_data` field, which will later allow for the sink to exist on the parser thread separately.

style: Be more strict when setting the root font size.
Before this commit, we assumed that if the element had no parent element, it was
the root of the document, which is plain false, since we can arrive there from,
let's say, getComputedStyle on a detached node.

Windows can run WPT
<!-- Please describe your changes on the following line: -->
This PR contains fixes that address the specific errors in #17392: WTP workarounds for Windows terminals (see #8313), modifications to `mach test --all` that allow `test_tidy` to be called properly, and modifications to the test harness for WPT that allow it to run when OpenSSL isn't found. How to handle OpenSSL on Windows is probably a separate issue because it doesn't have a straightforward answer: we either need to provide specific instructions to users or bundle it in binary form ourselves.

Servo backout testing
We deployed the Servo VCS backout service recently and want to test it. The goal is to land this PR so it is replicated to the Firefox repo. Then we'll back out this PR from the Firefox repo, which should trigger a new PR against Servo to do the backout.
The changed code is not wrong. So if things don't go as planned, it shouldn't harm anyone.

The current code is mostly bechmarking Rust's default hash routines for
integers, which is not interesting to us. We add generating function
that jumps around "enough" and also add benchmarks for clear().
It's hard to read too much into the numbers because we can't reliably
simulate L1/L2 cache behavior with cargo bench, but the results show
about 40ns for clear() about 2ns for insert, and about 1.5ns for
contains/remove. This informs our thinking in the next patch.
This is important because we're about to start storing a parallel list
of pushed hashes, and the current behavior here will cause mismatches
there.
We take the opportunity to bump the SmallVec size to 16, since each
entry is only a word and we really want to avoid heap-allocating. And
then we switch to drain(), because of

Right now when calling getComputedStyle with an element from another document,
we return the style using the pres context of that document, not of the document
of the window getComputedStyle was called on, so this holds.
But it will stop holding if we ever change this, so assert it doesn't happen.

Improve decisions in compositor over when to draw a frame.
This patch fixes a couple of issues in the compositor:
1) Remove the delayed composition code. Previously, this would schedule
a composite for 12ms in the future. This doesn't really make any sense
with WR. There's no point in doing a composite unless WR has provided
a new frame to be drawn. This fixes issues in several benchmarks where
we were doing multiple composite / renders per rAF, which is a waste
of CPU time. This *does* make the framerate slower in some cases (such
as a slow rAF callback) but it's more correct - otherwise we were just
compositing the same frame multiple times for no real benefit.
2) Inform the window of the current animation state of the compositor.
Specifically, if an animation (or rAF) is currently active, the
window system switches to use event polling, and does not block on
the OS-level event loop. In the case of active animation, we just
assume that we want to be running as the vsync interval and not
blocking. This means the compositor thread only sleeps on vsync
during animation, which reduces OS scheduling and results in much
smoother animation.
