[zhili03]

Description

Make pooling use stateless pooling op from ACL.

Checklist

General

• Do all unit and benchdnn tests (make test and make test_benchdnn_*) pass locally for each commit?
• Have you formatted the code using clang-format?

Performance improvements

• Have you submitted performance data that demonstrates performance improvements?

Thanks for the patch @zhili03. Could you please resolve the formatting failures?

Also nit: we usually prefix the aarch64 changes' commit messages with cpu: aarch64 rather than just cpu:. This makes it easier to grep for in the git logs as well.

Hi @Sqvid , thanks for it, will fix the format issue and commit messages in my next commit

Hi Zhibo, could you add performance numbers and the corresponding benchdnn command? Thank you!

Also, we need to remove the change id from the PR message and commit message thanks!

Hi Ryo, sure, will do in the next commit as well, thanks!

Hi @Sqvid @Ryo-not-rio some CI pipelines are failing because the stateless pooling function haven't been merge to ACL yet, does that mean this PR cannot be merged at least until next ACL's release? Thanks
