win-capture: Use FindWindowEx to traverse window list

Browse Source 
For some unknown reason, GetWindow will not traverse the entire window
tree.  It could be due to Microsoft purposely hiding certain UWP
windows, though the reason is unknown.  For some equally unknown reason
FindWindowEx does work in its place.

This fixes the issue of not being able to find/capture certain windows,
such as halo 5: forge.
