A convenience subclass of QWindow that provides a Vulkan-capable window with a double-buffered FIFO swapchain. While advanced use cases are better served by a custom QWindow subclass, many applications can benefit from having a convenient helper that makes getting started easier. Add also three examples of increasing complexity, and a variant that shows embeddeding into widgets via QWindowContainer. [ChangeLog][QtGui] Added QVulkanWindow, a convenience subclass of QWindow. Task-number: QTBUG-55981 Change-Id: I6cdc9ff1390ac6258e278377233fd369a0bfeddc Reviewed-by: Andy Nichols <andy.nichols@qt.io>
