feat: add optional hashbrown feature with foreign-type impls

Mirrors the std::collections::HashMap/HashSet impls for hashbrown::HashMap<K, V, S>
and hashbrown::HashSet<T, S>. Pulls hashbrown in only when the feature is enabled,
so non-feature users see no dependency.

Lets no_std users (where std::collections::HashMap/HashSet are unavailable) account
hash-collection memory through the same API.

Refactors fix_set_for_capacity / fix_map_for_capacity to take (type_size, len,
capacity) instead of a typed reference so the same Swiss-table layout helpers
service both std and hashbrown impls. Lifts cfg gates on GROUP_WIDTH,
capacity_to_buckets, and MemSizeHelper2 from "std" to any(std, hashbrown).

Hasher S is left unbounded: matches the std impl's behaviour of counting only the
inline hasher footprint.
