Add better tracing and fix propagation of inDesiredState for PSAdapter

[SteveL-MSFT]

PR Summary

• Tracing wasn't correct due to case-sensitivity of JSON and some traces were being written directly instead of through the helper
• Simple tracing should be lowercase and be warn instead of warning
• Add _inDesiredState property to the result object for test if any of the results contain InDesiredState and only true if all are true

Pull Request Overview

The PR updates the JSON key names used in logging to ensure proper trace level mapping and consistency.

• Converted JSON keys for error, warn, info, debug, and trace from uppercase to lowercase.
• Ensured the logger calls correctly use the lower-case keys as specified.

Need to make one more change to rename InDesiredState to _inDesiredState at the resource level to keep it consistent

Edit: Actually, maybe we'll keep it as-is for now so there's no manipulation of the source
