Diego de Souza 0c0580e5bf avcodec/cuviddec: add CUARRAY opaque output and zero-copy support 
Implement opaque block-linear output for the CUVID decoder, mirroring
the NVDEC hwaccel path but within the standalone CUVID demuxer/decoder.

Key additions:
  - output_format=cuarray option and zero_copy toggle
  - CUarray surface creation and cuvidRegisterDecodeSurfaces
  - Zero-copy path: frames reference decode CUarray surfaces directly
  - Copy path: output surfaces allocated from the hwcontext_cuda pool
  - Deferred decoder cleanup (CuvidDecoderCleanup) to handle the case
    where surfaces outlive the decoder due to encoder buffering
  - 444 chroma sw_pix_fmt remapping to semi-planar (NV24, P410, P412,
    P416) to match the native CUarray layout
  - Per-plane linesize derived from CUarray plane descriptors via
    cuArrayGetPlane / cuArray3DGetDescriptor
  - Crop, resize, and deinterlace forced off (with warnings) for
    cuarray output, as the decode surfaces are used directly

All opaque-specific code is guarded by NVDEC_HAVE_OPAQUE_OUTPUT_SUPPORT.
