The only remaining consumers are ::-moz-tree pseudo-elements (we used to
use ThinBoxedSlice for other data structures in the past).
Those are not particularly performance sensitive so I think just
double-boxing is fine. In the future, if we wanted to avoid the double
indirection, we could probably use the "thin" crate
(https://docs.rs/thin) or similar, which stores the length of the slice
along with the allocation, making the pointer thin in all
configurations, much like "ThinArc" does:

In practice though, I don't think it's particularly worth it for this
specific case.

This will ultimately make it simpler to update crate dependencies and
reduce duplicate when specifying requirements. Generally, this change
does not touch dependencies that are only used by a single crate. We
could consider moving them to workspace dependencies in the future.
- Also updates raqote to latest with an upgrade of font-kit to 0.11
applied on as a patch
- Update lyon_geom to the latest version
Major change:
- All matrices are now stored in row major order. This means that
parameters to rotation functions no longer should be negated.
- `post_...()` functions are now named `then()`. `pre_transform()` is removed,
so `then()` is used and the order of operations changed.
This implements the easy / straight-forward parts of the :where / :is
selectors.
The biggest missing piece is to handle properly invalidation when there
are combinators present inside the :where. That's the hard part of this,
actually.
But this is probably worth landing in the interim. This fixes some of
the visitors that were easy to fix.

This needs a lot more hooks before it'll actually be a good
implementation, but for a start it can help get some feedback on if this
is the right way to go about it.
