Summary

  • Removes the columnwise! operator implementation (src/Operators/columnwise.jl) and its CUDA extension (ext/cuda/operators_columnwise.jl)
  • Removes the associated unit test (test/Operators/finitedifference/unit_columnwise.jl)
  • Removes the corresponding includes from src/Operators/Operators.jl and ext/ClimaCoreCUDAExt.jl
  • Removes the "Unit: columnwise" and "Unit: gpu columnwise" buildkite CI jobs
    closes columnwise! is unused outside of the tests #2520

Test plan

  • using ClimaCore loads cleanly with no errors
  • Confirmed no remaining references to columnwise! or the deleted files elsewhere in the repo

Drops the CPU/GPU columnwise! implementation, its unit test, and the
associated buildkite CI jobs and includes.
