gdesktopappinfo: add g_desktop_app_info_launch_uris_as_manager_with_fds variant

Browse Source 
Add an app-launching function which allows standard file descriptors
to be passed to the child process.

This will be used by gnome-shell to pass systemd journal descriptors
as stdout/stderr. gnome-shell's child_setup function can then be
eliminated, which will enable use of the posix_spawn optimized
gspawn codepath for desktop app launching.
