refactor(yoko-core): remove finalizer from Acceptor_impl

Phase 3 of finalization refactoring: Remove finalize() method from
Acceptor_impl class.

- Removed finalizer that called close() and removed from listenMap_
- close() is already called explicitly in GIOPServerStarter classes
- listenMap_ cleanup was redundant as acceptors are explicitly managed
- Removed TODO comment about using phantom refs in AccFactory_impl
- Lines removed: 12

Tests: All yoko-core tests pass
