windows: Too long tooltip crashes

      In qtbase/gui/text/windows/qwindowsnativeimage.cpp there is a qFatal call if createDIBSection fails. And it can apparently fail if it is trying to create a bitmap for very wide tooltip.

      There probably isn't much we can do about that failing, but maybe there could be some artificial limit on tooltip size.

      To reproduce, run attached example.
