Winget-cli: Feature Toggle

[denelon]

Description of the new feature/enhancement

We need a feature toggle mechanism to allow new features to be built and released from the mainline at any time.

[megamorf]

The PowerShell team ships experimental features with their preview and stable builds. They are disabled by default and controlled by a json file called powershell.config.json
