New GPU Monitoring module doesn't report GPU usage on postpone

[Spiritreader]

Describe the bug
When a timed theme switch is delayed due to high GPU usage, the old monitoring module logged this incident.
The new module has been rewritten more efficiently and does not yet implement this behavior.

Expected behavior
The new GPU monitoring module logs the GPU usage once after the threshold has been surpassed with a message similar to the old module, e.g

Logger.Info($"postponing theme switch ({gpuUsage}% / {ConfigBuilder.Config.GPUMonitoring.Threshold}%)");

Additional context
Affected module: GPUMonitorModuleV2.cs
