Resolve issue with buttons on notifications not working correctly

[benhillis]

This pull request resolves an issue where the buttons on notifications were not working properly. This regressed with the introduction of the command line parsing helper class because this is difficult to test programmatically. There are three changes:

1. Pass arguments to wslhost.exe correctly (fix double -- character insertion)
2. Escape C:\Program Files\WSL\wslhost.exe path to resolve issue with space in the path name.
3. Fix issue where the COM embedding variable was incorrectly changed from -Embedding to --Embedding
4. NFC: Push logic to read disabled notification registry key into the TelemetryWorker method.

Resolves #13908

Pull request overview

This PR fixes a regression in notification button functionality that occurred after introducing a command line parsing helper class. The core issue involved incorrect argument formatting when spawning wslhost.exe from notification actions.

Key Changes:

• Fixed argument passing to wslhost.exe by removing double -- prefix and properly escaping the executable path
• Corrected COM embedding flag from --Embedding to -Embedding to match COM conventions
• Refactored telemetry worker to check notification registry settings lazily rather than at initialization
