What is changed and how it works?

This PR adds TiCI component support to tiup playground with the following improvements:

Key Features

• Separate TiCIMetaServer and TiCIWorkerNode instances: Each instance runs only one service for better resource management
• Proper startup sequence: TiDB → TiCDC → TiCI (meta then worker) → TiFlash
• TiCDC integration: Automatic changefeed creation with configurable S3 sink URI
• Environment variable support: TICDC_NEWARCH=true for TiCDC startup
• Unified configuration: Shared binpath and config parameters for both meta and worker instances

Usage

./bin/tiup-playground --pd 1 --kv 1 --db 1 --tiflash 1 \
  --db.binpath ~/Desktop/tidb/bin/tidb-server \
  --tiflash.binpath ~/Desktop/tiflash/cmake-build-debug/dbms/src/Server/tiflash \
  --ticdc 1 --ticdc.binpath ~/Desktop/ticdc/bin/cdc \
  --tici.meta 1 --tici.worker 1 --tici.binpath  ~/Desktop/tici \
  --tag your-cluster-name
