Add test case with ORCA query optimizer enabled

Adds test configuration for running regression tests with ORCA enabled:
- test: ic-good-opt-on
- make_configs: src/test/regress:installcheck-good
- pg_settings.optimizer: "on"

The ORCA query optimizer provides cost-based query optimization and offers
additional query optimization capabilities. This configuration allows
regression testing with ORCA enabled to verify optimizer functionality.
