decoder: simplify output of decoded frames.
...
Drop obsolete gst_vaapi_decoder_push_surface() that was no longer used.
Change gst_vaapi_decoder_push_surface_proxy() semantics to assume PTS
is already set correctly and reference count increased, if necessary.

decoder: fix possible leak of VA surfaces.
...
Under some circumstances, we could have leaked a surface, thus not
releasing it to the pool of available surfaces in the VA context.
The strategy is now to use a proxy earlier and automatically ref/unref
whenever necessary. In particular, during the lifetime needed for FFmpeg.
