BUG: Drop itkYvvBenchmark3D — input fixture 256x256x64.tif not available

Upstream benchmark referenced a 4 MB Input/256x256x64.tif blob that was
removed during ingest; no published ITKTestingData CID exists. 3D filter
coverage is retained by itkYvvWhiteImageTest3D and
itkGPURecursiveYvvGaussianImageFilterTest.
