Use hashlink over lru for LruCache (#8911)

Use the `LruCache` implementation provided by `hashlink` instead of the current `lru` one.
This is mostly a 1-to-1 swap with only slight API incompatibilities.
I have decided to leave some config files which previously used `NonZeroUsize` but they may not be required anymore and could potentially switch to `usize`.
