Make runs-on support variable expression (#29468)

As title.
Close issue: https://gitea.com/gitea/act_runner/issues/445
Follow: https://gitea.com/gitea/act/pulls/91

Move `getSecretsOfTask` and `getVariablesOfTask` under `models` because
of circular dependency issues.

(cherry picked from commit a1f5dd767729e30d07ab42fda80c19f30a72679f)
