feat: Add PaddleX service startup wrapper with adapter activation

- Introduced a new script to start PaddleX HTTP API service with automatic adapter activation.
- The script checks for environment variable to enable adapters and imports necessary functions from the adapters directory.
- Enhanced usability by allowing command-line argument parsing for PaddleX execution.
