Purpose

Seems introduced in #19928

But this function now is not used anywhere, not sure if we can delete it

Code Review

This pull request removes the file vllm/v1/attention/ops/pallas_kv_cache_update.py. After reviewing the provided context, I can confirm that this file appears to be unused, as there are no references to its functions (_kv_cache_update_kernel, kv_cache_update) in the rest of the codebase. Removing dead code is a good practice that improves maintainability. This change is a positive refactoring and appears safe to merge.

@yewentao256 thanks for catching this file. It should be deleted last time when tpu executor was removed.
