Jake Hillion c37eb24331 util: remove dead code (#1445) ...

The util crate contained several unused items: NonemptyArray,
BoxedSliceExt, a blanket Sealed trait, an empty alias module, six unused
nightly feature gates, and five unused Cargo dependencies (thiserror,
once_cell, internment, derive_more, bon, recursion).

Removed all items that had no references outside their own definitions,
keeping only WakerDeque, VecExt, and the trait_alias feature gate which
are actively used by the networking and exo_pyo3_bindings crates.

Test plan:
- CI
