[Cin] cingg hevc_vaapi rendering on Arc A750 gpu

[Terje J. Hanssen]

Two simple tests I got working Cinelerra Infinity - built: Sep  8 2024 
10:37:25 (rpm installation)
on Leap 15.6 on i7-12700KF + Arc A750 gpu

As seen below, quite fast rendering:

  * 207 fps for hdv.m2t  (yuv420p) input -> yuvj420p
  * 125 fps for proreshq.mov  (yuv422p10le) -> yuvj420p (10-bit  to
    8-bit color depth)
