gappinfo: Allow giving no GAppInfo for getting startup notify id

Browse Source 
On Wayland the activation token returned by
`g_app_launch_context_get_startup_notify_id()` doesn't depend on the
`GAppInfo`. The token is only used to hand over focus to the
application that is launched. In some cases it's not even possible to know
what application will actually be used to open the files. For example
when using portals within a sandbox. Therefore, allow providing no
`GAppInfo`.

This also makes clear in the docs that the `files` argument can be `NULL`.
