feat : Run MetaDrive simulation test in GitHub Actions

[mahmudsudo]

Description

This PR implements the requirements for running the MetaDrive simulation test reliably in GitHub Actions, addressing and closes #30693.

Changes include:

1. Real-time execution fix: Fixed a CPU starvation issue in test_sim_bridge.py where a while busy loop (continue) was consuming a full CPU core. On 2-core GitHub Action runners, this starved openpilot processes, causing the test to lag behind real-time and eventually timeout. Replaced with time.sleep(0.1) to allow Ratekeeper to maintain proper real-time execution.
2. Logs & Artifacts: Added a RECORD environment variable to launch_openpilot.sh to unblock loggerd and encoderd. This allows openpilot to capture qlog, rlog, and camera files during the simulation.
3. Execution setup: Made test_duration configurable via TEST_DURATION in test_metadrive_bridge.py.
4. CI Integration: Re-enabled the simulator_driving job in tests.yaml. It now runs for a full 60 seconds (TEST_DURATION=60), passes RECORD=1, and uploads the ~/.comma/media/0/realdata/ directory as a GitHub Artifact upon completion.

Verification

• Verified that the simulator_driving job now successfully completes 1 minute of driving without timing out on standard GitHub Action runners.
• Confirmed that Ratekeeper no longer lags behind real-time.
• Verified that the metadrive_logs artifact is correctly generated and contains the expected qlog, rlog, and .hevc camera files.
