g_object_info_find_method_using_interfaces: New function

Browse Source 
Pull this down into introspection from gjs; this will allow us
to cache this better in the future (for example, by caching the
infos for interfaces in the info for the object).

* Obtain a method of the object given a @name, searching both the

* Note that this function does *not* search parent classes; you will have

* Returns: (transfer full): the #GIFunctionInfo. Free the struct by calling
* g_base_info_unref() when done.
