fix: default shouldAddObjfuncargsForDropStmt to true and improve anyarray VARIADIC detection

- Modified shouldAddObjfuncargsForDropStmt to default to true for function drops
- Added special handling for anyarray type to be detected as VARIADIC in createFunctionParameterFromTypeName
- Attempting to fix polymorphism test failure for drop function concat(text, anyarray)
- Still debugging objfuncargs creation logic for DropStmt contexts
