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:
https://searchfox.org/mozilla-central/rev/1ce2eea39442190a71a1f8f650d098f286bf4a01/servo/components/servo_arc/lib.rs#891
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.
Release selectors 0.24.0 and servo_arc 0.2.0
This patch extends #29361, bumping selectors to 0.24.0 and servo_arc to 0.2.0.
We’ll need to publish them too, in order to close#29105.

We still panic in a debug build, so that developers can notice when they
need to add a new static atom after modifying UA sheets.
We also add telemetry to note when this happens, add an app note to a
crash report, in case any crash later on occurs, and re-up the existing,
expired shared memory sheet telemetry probes so we can look at them
again.
