No change in functionality.

This patch refactors six ancestor-finding methods in AXCoreObject from pure virtual, template-based implementations to non-virtual inline member functions. The refactoring improves const-correctness, simplifies the inheritance hierarchy, and eliminates virtual dispatch overhead.

In both derived classes, removed simple forwarding functions to the template implementations. With the base class now providing concrete implementations, these overrides are no longer needed.
