Vulkan: Recreate an additional swapchain that stays suboptimal

Browse Source 
Only out of date and a lost surface recreated one, so a TV whose mode
changed without a resize (MoltenVK reports SUBOPTIMAL when the layer's
size no longer matches) kept a stretched picture. Like the main
swapchain, it's now recreated after a few SUBOPTIMAL presents in a row.
