  ffv1enc_vulkan: use ff_get_encode_buffer
  
  We used to create our own buffer, but still used the DR1 flag,
  which is not how it's supposed to work.
  
  Instead, use ff_get_encode_buffer, and either host-map the buffer
  before copying each slice via GPU transfers, or just copy each
  slice manually if that fails or is unavailable.
