feat: log shadow mode through engine reporting API

[jye-sf]

Details

Adds telemetry for shadow mode usage (synthetic vs native). Due to the volume of logs this is going to generate (easily TBs), we'll want to report this as a metric rather than as logs. We will do this in the consuming app container. (e.g. if (reportName === 'ShadowModeUsage') { ... }).
