We move the codec specific bits to their own respective files and now make the codec specific initialisation use a GstBin, which the generic GStreamer module now uses in the pipeline. It is job of the codec specific function to add elements in the GstBin and link the added elements in the bin. It should also set up the ghost pads as a GstBin has no pads of it's own and without which the bin cannot be linked to the appsrc/appsink. Also, we now only initialise either the encoding or the decoding pipeline and not both. The codec init API already gets passed the for_encoding flag. We pass and use the same to codec specific init functions. Part-of: <https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/440>
