tdf#119947 vcl opengl win: fix fontwork popup menu
Regression from commit b160db926b574b7e9d6696d49dbbce8dd289aade
(tdf#96947 vcl opengl win: fix background of menu items w/ check/radio
marks, 2018-05-14), the problem was that GetMenuPopupMarkRegion() did an
unconditional downcast from ImplControlValue to MenupopupValue. This
looked safe, but when the extracted function was used in
WinSalGraphics::drawNativeControl(), then that argument was not safe to
downcast.
Fix the problem by switching to safe downcast, and returning an empty
rectangle (instead of a bogus one) on error.
This way the old bug stays fixed but fontwork popup menu works again as
well.
