ts/pad: use gst::Pad in handlers trait functions...

Browse source 
... instead of the `Pad{Src,Sink}Ref` wrappers:

- In practice, only the `gst::Pad` is useful in these functions.
  Some of these which need a `Pad{Src,Sink}Ref`, but it's the one
  for the opposite stream direction. In those cases, it is accessed
  via the element's implementation.
- It saves a few `clone`s.
- The implementations usually use the `gst::Pad` for logging.
  They no longer need to access it via `pad.gst_pad()`.
