fix(telemetry): add result parameter when emitting telemetry

[opieter-aws]

Problem

Users are seeing telemetry: invalid Metric: "codewhisperer_clientComponentLatency" emitted without the resultproperty, which is always required. Consider using.run()instead of.emit(), which will set these properties automatically. See https://github.com/aws/aws-toolkit-vscode/blob/master/docs/telemetry.md#guidelines

Solution

Add result attribute when emitting the metric
