Don't make logical properties animatable
|animation_type| was renamed in 94fb839fdd, but the commit missed renaming
one place. It means that some of logical properties might have been
accidentally animatable. Logical properties should be animatable but we
haven't yet implemented the proper Animate trait for logical properties.

We could invalidate in a slightly more fine-grained way, but I don't think it's
worth the churn vs. keeping the special-cases minimal.

style: Implement the non-functional :host selector.
Kinda tricky because :host only matches rules on the shadow root where the rules
come from. So we need to be careful during invalidation and style sharing.
I didn't use the non_ts_pseudo_class_list bits because as soon as we implement
the :host(..) bits we're going to need to special-case it anyway.
The general schema is the following:
* Rightmost featureless :host selectors are handled inserting them in the
host_rules hashmap. Note that we only insert featureless stuff there. We
could insert all of them and just filter during matching, but that's slightly
annoying.
* The other selectors, like non-featureless :host or what not, are added to the
normal cascade data. This is harmless, since the shadow host rules are never
matched against the host, so we know they'll just never match, and avoids
adding more special-cases.
* Featureless :host selectors to the left of a combinator are handled during
matching, in the special-case of next_element_for_combinator in selectors.
This prevents this from being more invasive, and keeps the usual fast path
slim, but it's a bit hard to match the spec and the implementation.
We could keep a copy of the SelectorIter instead in the matching context to
make the handling of featureless-ness explicit in match_non_ts_pseudo_class,
but we'd still need the special-case anyway, so I'm not fond of it.
* We take advantage of one thing that makes this sound. As you may have
noticed, if you had `root` element which is a ShadowRoot, and you matched
something like `div:host` against it, using a MatchingContext with
current_host == root, we'd incorrectly report a match. But this is impossible
due to the following constraints:
* Shadow root rules aren't matched against the host during styling (except
these featureless selectors).
* DOM APIs' current_host needs to be the _containing_ host, not the element
itself if you're a Shadow host.

It doesn't actually matter because this is only called from
WebGLRenderingContext::BindTexture, which already checks the target,
but better be safe than sorry.
The early return for identical setting in importance matching as well
as the comment before `index_to_remove` are removed because the order
is web-exposing regardless of whether it's from CSSOM or parsing. e.g.
`top: 1px; left: 2px; top: 1px;` is effectively `left: 2px; top: 1px;`,
not `top: 1px; left: 2px;`.
Add support for percentages in column-gap.
<!-- Please describe your changes on the following line: -->
# Changes in this PR
* I've removed the `if product == "gecko"` line in order to make the column_gap type "NonNegativeLengthOrPercentageOrNormal" always.

```rust
Either::First(len) => len.into(),

to
```rust
Either::First(len) => len.0.to_pixel_length(content_inline_size).into(),
