Add portal support to g_app_info_launch_default_for_uri

We need to patch in the portal support at a high enough
level that GAppInfo is not involved - a sandboxed app may
not be able to see any applications, so it can only launch
the defaults.

Note that even though the API is called launch_default...,
the portal may still offer the user to choose the application
to launch.
