[moooyo]

Summary of the Pull Request

Clean up some AOT build issue. Currently, we can not build the Advanced Paste module with AOT enabled.

blocker:

1. We need to upgrade CommunityToolKit.WinUI to the latest preview version. It provide native AOT support. https://github.com/CommunityToolkit/Windows/releases/tag/v8.2.241112-preview1
2. CommunityToolKit.Mvvm provide more AOT diagnostic info in 8.4.0. But I'm not sure wether it provide Native AOT support for our project. https://github.com/CommunityToolkit/dotnet/releases
3. ReverseMarkdown does not support Native AOT

Suggested change

	public string ToJsonString() => JsonSerializer.Serialize(this, AdvancedPasteJsonSerializerContext.Default.PersistedCache);
	public string ToJsonString() => JsonSerializer.Serialize(this, AdvancedPasteJsonSerializerContext.Default.LogEvent);

Also, I believe the LogEvent class should be more defined.

Since we know telemetryEvent.CacheUsed, telemetryEvent.IsSavedQuery, telemetryEvent.PromptTokens, telemetryEvent.CompletionTokens, telemetryEvent.ModelName, telemetryEvent.ActionChain are the properties passed into the anonymous object, defining them in the class will make it cleaner and less prone to potential issues.
