[CI] Use devops dir from sycl on sycl-rel nightly

[KornevNikita]

To keep sycl-rel nightly testing up to date we need to use devops/actions from sycl branch. This change adds new input to specify the ref for devops dir checkout.

Note for reviewers: just aligned this with sycl-linux-build.yml

[KornevNikita]

another option - may be we can drop ref at all so actions/checkout@v4 will use github.sha as by default.

I think we still [want to] have CUDA on AWS testing. Due to its setup it can't use pull_request trigger and uses pull_request_target trigger. IIUC, the ref input is mostly to support such scenario (although I might be wrong here).

[KornevNikita]

I guess you mean this one? As I understand it's not used for ~6months and we don't have AWS runners anymore or? Nick made these changes, so @sarnex can we just drop ref args at all? Like

Suggested change

ref: ${{ inputs.devops_ref || inputs.ref }}

[aelovikov-intel]

We still run it in Nightly:

llvm/.github/workflows/sycl-nightly.yml

Lines 147 to 169 in f3d12f0

	sycl_toolchain_decompress_command: ${{ needs.ubuntu2204_build.outputs.artifact_decompress_command }}

because we don't want the infrastructure support to rot.

[sarnex]

do we ever want this to be different? shouldnt we always use the current version from the sycl branch?

[KornevNikita]

Not sure. So this first checkout defines which devops/actions/cleanup and devops/actions/cached_checkout scripts are used. Are there cases when you need to use the script from your branch, not from sycl, e.g. If you need to test changes in cached_checkout?

[sarnex]

ive never had to, since we should always use the workflow/script in the current PR which is always what i wanted

[KornevNikita]

@sarnex @aelovikov-intel so i'm a bit confused - what should I do here? just stay with the introduced solution or change something?

[sarnex]

if we don't need devops_ref for this to work i would prefer we remove it and always use sycl branch head

[aelovikov-intel]

if we don't need devops_ref for this to work i would prefer we remove it and always use sycl branch head

How are we going to test changes in devops/actions/run-tests/e2e/action.yml then?

[sarnex]

ah yeah i see, we can't use ref like we do for normal PRs because the PR may be from the sycl-rel branch, this pr is fine then
