[New Feature]: Platform detection

[OfficialEsco]

Description of the new feature/enhancement

This one should probably be pretty easy tbh, any appxbundles should be tagged as - Windows.Universal while the rest gets tagged as - Windows.Desktop

Alternatively take a look at how wingetcreate does it

Proposed technical implementation details (optional)

No response

@jedieaston - Would you be able to point me where in wingetcreate source code to look at this?

[jedieaston]

It looks like wingetcreate doesn't even try. If it isn't set in the old manifest and the user didn't manually specify it somehow, then it's null.
