Remove VDPAU plugin

Browse source 
It's been replaced by NVENC/NVDEC and even NVIDIA doesn't
support VDPAU any longer and hasn't for quite some time.

The plugin has been unmaintained and unsupported for a very
long time, and given the track record over the last 10 years
it seems highly unlikely anyone is going to make it work well,
not to mention adding plumbing for proper zero-copy or
gst-gl integration.

Closes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/828
