Adds comprehensive benchmark tests for Zarr v2 format.

  • Tests reading/writing performance on Zarr v2 arrays
  • Tests with different compression (none, gzip) and chunk layouts
  • Tests on both memory and local file stores
  • V2 benchmark suite (no shards, only traditional chunking)

All validation passed locally (5300+ tests).

i think it would be better to re-use our existing indexing tests, but with a parametrization that hits the zarr v2 path

Closing: superseded by PR #3818 which implements the suggested parametrized approach. This PR uses the old separate test file approach.
