[CI] Don't rely on github.event_name in devops/actions/run-tests/e2e/action.yml (#20580)

This effectively reverts

"[CI] Use E2E container binaries in `run-only` manual E2E task dispatch
(#19744)"

The problem is that `github.event_name` corresponds to the top-level
workflow, not how `.github/workflows/sycl-linux-run-tests.yml` was
triggered, effectively doing the wrong thing for the manual dispatch of
(at least) post-commit workflow.

Instead of that, add a new fake input parameter for the `workflow_call`
trigger in `sycl-linux-run-tests.yml` to use as the condition.
