Update plugin elements with the new GstVaapiVideoMeta API. This also fixes support for subpictures/overlay because GstVideoDecoder generates a sub-buffer from the GstVaapiVideoBuffer. So, that sub-buffer is marked as read-only. However, when comes in the textoverlay element for example, it checks whether the input buffer is writable. Since that buffer read-only, then a new GstBuffer is created. Since gst_buffer_copy() does not preserve the parent field, the generated buffer in textoverlay is not exploitable because we lost all VA specific information. Now, with GstVaapiVideoMeta information attached to a standard GstBuffer, all information are preserved through gst_buffer_copy() since the latter does copy metadata (qdata in this case).
