avutil/pixfmt: add AV_PIX_FMT_CUARRAY for opaque CUDA block-linear surfaces

Browse Source 
Add a new hardware pixel format representing opaque block-linear CUDA
arrays (CUarray). This format is used by NVDEC when decoding into
opaque surfaces registered with cuvidRegisterDecodeSurfaces, and can
be consumed directly by NVENC as CUDA array input without requiring
a pitch-linear copy.
