[vulkan] Recreate the surface on surface loss.

Browse Source 
According to the Vulkan spec:

> Several WSI functions return `VK_ERROR_SURFACE_LOST_KHR` if the
> surface becomes no longer available. After such an error, the surface
> (and any child swapchain, if one exists) **should** be destroyed, as
> there is no way to restore them to a not-lost state.

So if we get this error, we need to recreate the surface in addition to
the swapchain.
