[CI] Add precompiled CTS tests to sycl_prebuilt_tests image

[ianayl]

This PR adds precompiled CTS binaries to sycl-prebuilt-e2e-container.yml.

Note that this PR also renames some fields in devops/actions/run-tests/cts/action.yml to match that of run-tests/e2e/action.yml. If this is unwanted I will undo the changes.

Test run at https://github.com/intel/llvm/actions/runs/18386413684

CTS tests are running as expected, but there seems to be a single failure. It doesn't seem to be related to the workflow, but I still need to look into why it is failing.

Let's also update the description in sycl-prebuilt-e2e-container.yml:

llvm/.github/workflows/sycl-prebuilt-e2e-container.yml

Lines 3 to 5 in dabf72a

	# The purpose of this is to build E2E tests with the latest release toolchain
	# and then run them with the trunk SYCL RT (libsycl.so and friends) to verify
	# that ABI compatibility hasn't been broken.

This is actually broken in run-tests/e2e/action.yml (I found out today), but I don't have a fix yet. In a nutshell, github_event_name corresponds to the top-level workflow (i.e., pull_request/workflow_dispatch/push) and not to how the sycl-linux-run-tests.yml has been invoked (dispatch vs call).

#20580 fixes it in trunk, this PR will need to be updated.

Manual run: https://github.com/intel/llvm/actions/runs/18959457462/job/54145504511

All CTS tests seem to be seg. faulting.

@aelovikov-intel That run seems to be using the main branch in intel/llvmI misread, you seemed to have used a hash; Do you happen to know what version the commit hash is from?

On HEAD in sycl, both main and hardcoded commit from sycl-rel-6_3 works:
