### What this PR does / why we need it?
- Pass GITEE_USERNAME (var) and GITEE_TOKEN (secret) as Docker build
args in nightly image build so Dockerfile can authenticate to Gitee
- In Dockerfile.nightly.a2/a3, embed credentials into clone URL to
avoid auth failure during `git clone`
- In single-node and multi-node PR test workflows, backup the
pre-installed benchmark from the nightly image before wiping
vllm-ascend, then restore it instead of re-cloning from Gitee,
which is inaccessible from fork PR contexts
### Does this PR introduce _any_ user-facing change?

### What this PR does / why we need it?
- This PR removes several self-hosted runner labels from the
`actionlint.yaml` configuration file. These runners are likely no longer
in use, so this change cleans up the configuration and ensures
`actionlint` has an accurate list of available runners.
- Move all Action dockerfiles to one folder
- remove useless `runner` input for e2e test.
- update workflow option version
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
This is a configuration change for the CI linter. The correctness will
be verified by `actionlint` running in CI on subsequent pull requests.
