[GTK][Introspection] GObject bindings for DataTransferItemList - one add() method must be removed from .idl
https://bugs.webkit.org/show_bug.cgi?id=109180

Reviewed by Xan Lopez.

When compiling WebKit with --enable-introspection and generating GObject bindings
for DataTransferItemList we must disable one add() method, because GObject is
based on C and C does not allow two functions with the same name.

No tests needed.
