shiboken: Fix exception handling when specified in base class

Class-level exception specifications on a base class were not working
so far. This requires a larger refactoring, since the base classes are
not yet known at the point where class functions were traversed
(AbstractMetaBuilder::setupInheritance() is called at a later stage).

To fix this, store the actual type system modification in the
AbstractMetaFunction and move the logic determining whether to
generate exception handling into
AbstractMetaFunction::generateExceptionHandling(). In this function,
recurse down the base classes if the function does not have a
modification set.

This is a preparation for giving the allow-thread attribute, which can
currently only be used at a function level, a similar handling.
