Sreerenj Balachandran e66e72e7e3 decoder: add support for video cropping.
Add gst_vaapi_picture_set_crop_rect() helper function to copy the video
cropping information from raw bitstreams to each picture being decoded.
Also add helper function to surface proxy to propagate that information
outside of libgstvaapi. e.g. plug-in elements or standalone applications.
