Windows QPA: Cache "forcedScreenForGLWindow" to avoid overhead
The fix for QTBUG-50371 caused an overhead when you hover over a
secondary window like a tool tip, menu or combo box due to the
forcedScreenForGLWindow() function being called, which loads
dx9.dll and sub-dlls and unloads them afterwards. This fix
caches the required info on the first call, and only refreshes
it when required by a display/settings change.
Fixes: QTBUG-73008
