vulkan/wsi: Add wsi_common_is_swapchain_image() helper

Browse source 
Add a helper function to check if a VkImageCreateInfo represents a
swapchain image by looking for VkImageSwapchainCreateInfoKHR in the
pNext chain.

This consolidates the swapchain detection logic that is currently
duplicated across all Vulkan drivers, and handles the Android case
in one place.
