Detailed Description of the Pull Request / Additional comments

With the new monitor identification code, FancyZones was failing in cases where EnumDisplayDevicesW didn't detect any monitors connected to a display device.
It also looks for the active monitor inside each display device since it's possible for a monitor to be inactive and the correct one for the display will be another monitor connected to the display device.

Validation Steps Performed

Asked the users from the issues to test it on their configurations, since I've got no physical or virtual machine capable of replicating the same conditions for the users.

tested on my setup, couldn't reproduce the issue neither before or now. Change looks good.
