wsi/common: Set VK_IMAGE_CREATE_ALIAS_BIT

With Vulkan 1.1, we have a VkImageSwapchainCreateInfoKHR struct which
lets you create a new VkImage which aliases a swapchain image.  However,
there is no corresponding swapchain create flag so we have to set
VK_IMAGE_CREATE_ALIAS_BIT all the time.

We need to do a bit of work in ANV to prevent it from asserting the
moment it sees one of these.  Fortunately, they're already safe because
WSI images go through a different bind path for
VkBindImageMemorySwapchainInfoKHR.
