feat(autoware_processing_time_checker): add a trigger to choice whether to output metrics to log folder

[xtk8532704]

Description

Add a bool parameter output_metrics, if it's true, the autoware_processing_time_checker node writes the statics of the processing_time measured during its lifetime to <ros2_logging_directory>/autoware_metrics/<node_name>-<time_stamp>.json when shut down.

This feature will be used to collect and analyze test results in real vehicle tests and evaluator tests.
