Enable the const_refs_to_static Rust feature to allow taking
references to static items in const contexts. This is required for
using ThisModule when constructing static Rust structures.

The Rust support already relies on features available in Rust 1.83, and
const_refs_to_static has been available since Rust 1.78.
