[PTRun]Detect full-screen games with QUNS_RUNNING_D3D_FULL_SCREEN (#30797)

Browse Source 
* Add SHQueryUserNotificationState to NativeMethods

* Check for QUNS_RUNNING_D3D_FULL_SCREEN in IsWindowFullscreen

The current test for whether a window is full-screen (i.e. a movie or a game) is a bit of a heuristic. In certain cases however, we can *know* that a window is full-screen. Check that case first, then proceed with the existing logic

* Make spellchecker happier
