fileserver: migrate pingcap/tiproxy artifacts to OCI registry (#4273)
- [x] Explore codebase and understand migration pattern - [x] Remove `FILE_SERVER_URL` from all 16 tiproxy pipeline groovy files - [x] Replace `download_binary.sh` with `download_pingcap_oci_artifact.sh` in all 16 groovy files - [x] Add `utils` container to all 15 existing tiproxy pod YAML files - [x] Create missing `pod-merged_integration_sequelize_test.yaml` (with golang, nodejs, utils, net-tool containers) - [x] Verify no remaining `fileserver.pingcap.net` references in tiproxy pipelines - [x] Remove redundant `sh "mkdir -p bin"` step from all 16 groovy files (dir() creates the directory automatically) - [x] Add `OCI_ARTIFACT_HOST = 'hub-zot.pingcap.net/mirrors/hub'` environment variable to all 16 groovy files
