Equivalent to g_desktop_app_info_launch_uris_as_manager() but allows you to pass in file descriptors for the stdin, stdout and stderr streams of the launched process.
If application launching occurs via some non-spawn mechanism (e.g. D-Bus activation) then @stdin_fd, @stdout_fd and @stderr_fd are ignored.
