[TIMOB-25015] Windows: Allow a user to check the Windows 10 Device Family

Description

This is mainly for the test suites but it seems like something that might be seen as nice from a users standpoint too. (Although in reality on UWP a developer should not be tying features to a device family but using the detecting API contracts https://blogs.windows.com/buildingapps/2015/09/15/dynamically-detecting-features-with-api-contracts-10-by-10/, which maybe we should also have an API for?) Basically in the tests we have to skip some tests on a device family because they prompt, Geolocation primarily, currently this is skipped on emulator easily by checking the model but a device is harder to check. We could skip both in one go by doing a check like Ti.App.Windows.deviceFamily() === 'Windows.Mobile' There is some demo code on how to do this here https://gist.github.com/wagonli/40d8a31bd0d6f0dd7a5d but note that it looks the DeviceFamily prop isn't documented https://docs.microsoft.com/en-us/uwp/api/windows.system.profile.analyticsinfo Personally I'm not sure whether this should be in core, maybe in a native module or HL module
