Description
When closing the QVulkanWindow, a validation error message will popup if validation layer enabled. It says
vkDestroySurfaceKHR(): called before its associated VkSwapchainKHR was destro yed. The Vulkan spec states: All VkSwapchainKHR objects created for surface must have been destroyed prior to destroying surface (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkDestroySurfaceKHR-surface-0 1266)
Seems like Vulkan Surface is destroyed before Swapchain is destroyed.
To reproduce,
- compile and run the `hellovulkantriangle` example
- close the window by click the close button on title bar
- the error messages show in the terminal:
vkDebug: Validation Error: [ VUID-vkDestroySurfaceKHR-surface-01266 ] Object 0: handle = 0x5f57e2117ef0, type = VK_OBJECT_TYPE_INSTANCE; | MessageID = 0xbed408e4 | vkDestroySurfaceKHR(): called before its associated VkSwapchainKHR was destroyed.

(btw, sorry for my username which was set long long ago for the annoying user registration when downloading community edition of Qt. I'd like to change one but I found it impossible on this site bugreports.qt.io)
