shiboken6: Skip base functions for which no bindings should be generated

Factor out a function for checking the bindings generation
and use that in getInheritedOverloads() as well.

Amends b1b2cc2ebed2fcf6e31c1fbbdd3638216e34717b, which caused
some modified-removed functions to be generated in derived
classes.

Pick-to: 6.1
