mediamanager: register static elements
These are source/sink elements which aren't dynamically inserted or
removed as the devices managed by GstDeviceMonitor come and go. Namely
they are default source and sinks (which represent their respective
"autodetect" GStreamer elements), audio and video test signal sources,
and video outputs (XVideo, OpenGL, DirectDraw, etc.).
