reduz e772b65d92 Remake resource thread safety and API
* Ensures thread safety when resources are destroyed.
* Simplified API by always forcing `ResourceCache::get_ref`, which needs less hacks and is fully thread safe.
* Removed RWLock for resources because its not possible to use for the new logic. Should not be a problem.
