introspection: Re-add platform specific APIs to GLib-2.0.gir and Gio-2.0.gir

Browse Source 
To avoid a big introspection API break.

These APIs are now listed in the new `{GLib,Gio}{Unix,Win32}-2.0.gir`
files, but for backwards compatibility they need to continue to be
listed in `Gio-2.0.gir` and `GLib-2.0.gir` as well, until the next major
introspection API break (and none is planned).

No new platform specific APIs should be added to these GIR files, but
these existing ones must remain.

See https://gitlab.gnome.org/GNOME/glib/-/merge_requests/3892#note_2001361
