[iron] Gracefully handle SIGINT and SIGTERM signals for play and burst CLI (backport #1557)

[mergify]

• Depends from Fix for false negative tests in rosbag2_py #1592
• Intercept signals to call Player::stop() instead of relying on the rclcpp::shutdown() in default signal handlers.
• Also added static Player::Cancel() method.
• Added test coverage for Cancel during playback. Note: adding unit test coverage for Cancel during burst is not feasible because it runs very fast without delays between messages and without a repetition option.
