Add a Clearcut tool event logger

Implement a binary that logs tool events to Clearcut. The binary is designed to be eventually called by the `run_tool_with_logging` script in the `envsetup.sh` script that sets up the build environment.

Only start and stop events are currently logged for each invocation.

Test: atest tool_event_logger_test
