Refactor commit status for Actions jobs (#23786) (#24060)

Backport #23786

Refactor commit status for Actions jobs (#23786)

Highlights:
- Treat `StatusSkipped` as `CommitStatusSuccess` instead of
`CommitStatusFailure`, so it fixed #23599.
- Use the bot user `gitea-actions` instead of the trigger as the creator
of commit status.
- New format `<run_name> / <job_name> / (<event>)` for the context of
commit status to avoid conflicts.
- Add descriptions for commit status.
- Add the missing calls to `CreateCommitStatus`.
- Refactor `CreateCommitStatus` to make it easier to use.
