Function xc_is_callable
Equals is_callable() but also supports Core class extensions.
The support for attached methods requires Core\Object to
implement __call(), hence is_callable() always returns true
for objects of classes inherited from Core\Object with any
method name. To circumvent this problem, this function checks whether
__call() is implemented by a descendant of Object, and if not
tests whether a method of the tested name has been attached to the class.
