Optionally Add `@ObservationIgnored` to `ObservableObject` Lazy Properties

[bcapps]

Feature Proposal

Add a flag to the command to mark any lazy property in an ObservableObject as @ObservationIgnored, as otherwise lazy properties will cause build errors now. Decide whether it should be enabled or disabled by default.

Acceptance Criteria

• A flag for this exists on ObservableConverterCommand and can be sent to Arguments when running
• The flag does the conversion to mark every lazy property in an ObservableObject as @ObservationIgnored
