Optimize gst_vaapiencode_handle_frame() to avoid extra memory allocation, and in particular the GstVaapiEncObjUserData object. i.e. directly use the VA surface proxy from the source buffer. This also makes the user data attached to the GstVideoCodecFrame more consistent between both the decoder and encoder plug-in elements.
