The original design of TypeConverter expected specific converters to derive the class and override virtual functions for conversions and materializations. This did not scale well to multi-dialect conversions, so the design was changed to register a list of converter and materializer functions, removing the need for virtual functions. The only remaining virtual function, `convertSignatureArg` is never overridden in-tree. Make it non-virtual, drop the virtual destructor and thus remove vtable from TypeConverter. If there exist TypeConverter users that need custom `convertSignatureArg` behavior, it should be implemented using the callback registration mechanism similar to that of conversions and materializations.
