Enable git trace2 event format logging.

Ways to enable logging:
1) Set git's trace2.eventtarget config variable to desired logging path
2) Specify path via --git_trace2_event_log option

A unique logfile name is generated per repo execution (based on the repo session-id).

Testing:
1) Verified git config 'trace2.eventtarget' and flag enable logging.
2) Verified version/start/end events are expected format:

3) Unit tests
