[Bugfix][CI] Fix aisbench installation to avoid Gitee authentication (#7536)

### 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?

### How was this patch tested?

- vLLM version: v0.18.0
- vLLM main:
