[Cin]Adding Vulkan presets to Intel oneVPL

Late 2024 onevpl support was added  for the buildsystem with various presets using cin_hw_dev=vaapi. Maybe I simplify too much, but is it possible that current CinGG-20251121-x86_64.AppImage with ffmpeg-8 is ready to test vulkan the same way, just by replacing "vaapi" with "vulkan" in the presets? hevc_vaapi_8b420.mp4     mp4 hevc_vaapi     cin_hw_dev=vaapi     cin_pix_fmt=nv12     profile=main     # global_quality=22 hevc_vaapi_10b420.mp4     mp4 hevc_vaapi     cin_hw_dev=vaapi     cin_pix_fmt=p010le     profile=main10     # global_quality=22 hevc_vaapi_10b422.mp4     mp4 hevc_vaapi     cin_hw_dev=vaapi     cin_pix_fmt=y210le     profile=rext     # global_quality=22 Terje J.
