[0.4.7][WIN32K] Implement UOI_FLAGS in NtUserGetObjectInformation().

Browse source 
Based from a patch by Jérôme Gardou.
Fixes CORE-13447 CORE-14422 CORE-14287

This fixes closing nLite 1.4.9.3 (.NET2) application, as well as any
other program that expects that the interactive window station is
reported as being visible. I thank Mark Jansen and Joachim Henze for
help and testing.

It regressed by SVN r74005 == git
d2f5096281

The fix was picked from 0.4.9-dev-750-g
