These imports need to be cfgd behind the feature flag

Use of dep: syntax requires Rust 1.71, so we should bump the rust-version if we're going to do this. I think this should be fine for string_cache? But perhaps worth noting I had to revert to the older feature syntax for crates like euclid that have lower MSRVs.

I would personally be tempted to do a manual impl here to avoid the dep on the derive crate (but I suspect my opinion will be a minority one here so this is more of a "noted dissenting opinion" rather than a request for a change).
