  ffv1: add a Vulkan-based decoder
  
  This patch adds a fully-featured level 3 and 4 decoder for FFv1,
  supporting Golomb and all Range coding variants, all pixel formats,
  and all features, except for the newly added floating-point formats.
  
  On a 6000 Ada, for 3840x2160 bgr0 content at 50Mbps (standard desktop
  recording), it is able to do 400fps.
  An Alder Lake with 24 threads can barely do 100fps.
