eventlog: Add a log type for Chrome OS diagnostics

Add events for Chrome OS diagnostics in eventlog tool:
* ELOG_TYPE_CROS_DIAGNOSTICS(0xb6): diagnostics-related events
* ELOG_CROS_LAUNCH_DIAGNOSTICS(0x01): sub-type for diagnostics boot

These events are not added anywhere currently. They will be added in
another separate commit.
