Merged

Why are these changes needed?

This updates includes a few fixes for image classification benchmarks:

  • use Dataset.map instead of Dataset.map_batches. [data] Implement zero-copy fusion for Read op #38789 ensures these will get fused with the Read, but map_batches also has some batch formatting overhead.
  • fix a bug in the benchmark related to image array dimensions
  • avoid a copy in the map transform
