AK: Add missing GenericTraits<NonnullRefPtr>

This enables us to use keys of type NonnullRefPtr in HashMaps and
HashTables.

This commit also includes fixes in various places that used
HashMap<T, NonnullRefPtr<U>>::get() and expected to get an
Optional<NonnullRefPtr<U>> and now get an Optional<U*>.
