Widgets/qwidgetbackingstore.cpp: Fix developer build with MinGW

Browse Source 
In  showYellowThing_win(), replace the switch by an array of COLORREF
and simplify the code accordingly, fixing:

kernel\qwidgetbackingstore.cpp: In function 'void showYellowThing_win(QWidget*, const QRegion&, int)':
kernel\qwidgetbackingstore.cpp:188:39: error: 'brush' may be used uninitialized in this function [-Werror=maybe-uninitialized]
         FillRect(hdc, &winRect, brush);
                                       ^
