perf scripts python: Extact necessary information from process event
The script takes in a sample event dictionary(param_dict) and retrieves
relevant data such as time stamp, PID, TID, and comm for each event.
Also start time is defined as a global variable as it need to be passed
to trace_end for gecko meta information field creation.
