plugins: streamline VA formats exposed in caps to a realistic set.

Currently, the decoder only supports YUV 4:2:0 output. So, expose the
output formats for GStreamer 1.2 in caps to a realistic subset. This
means NV12, I420 or YV12 but also ENCODED if we cannot determine the
underlying VA surface format, or if it is actually not allowed to get
access to the surface contents.
