va: filter, deinterlace, vpp: Add gst_va_buffer_get_surface_flags().

Browse source 
Add a helper function to get, from GstVideoInfo and GstBuffers flags,
the VA interlace surface flags. This is used currently by vainterlace
element, but it will be used in vapostproc too if it can process
interlaced frames.
