Support `OptionalFeatureList` and `FeatureOnDemandList` via winget-installed DSC

Summary of the new feature / enhancement

Hello! I noticed that in the v3.2.0 release notes that the Microsoft.Windows/OptionalFeatureList and Microsoft.Windows/FeatureOnDemandList DSC resources "[require] using the ZIP package of DSC for now".

I was unable to find an open issue about this, and I did confirm that this is still an issue when using DSC-3.3.0-preview.4-Win.msixbundle:

Microsoft.Windows/OptionalFeatureList🛡  [WindowsOptionalFeatures]

@SteveL-MSFT - I could find you doing a backport in this pull request,, but without a reason. Is this something unsolveable as of today?

@natescherer @Gijsreyn - I'm guessing that this'll likely be due to the same reasons why PowerShell can't use the DISM PowerShell module when installed via an msixbundle & is a know blocker in the 7.7.x releases

Seems to require Windows Changes/MSIX changes to resolve so nothing can be done in here yet AFAIK
