vulkan: allocate host-visible memory for swapchain images

vulkan: allocate host-visible memory for swapchain images

The Vulkan 1.2 specification, section 11.2.12 ("Host Access to Device
Memory Objects") say the following:

> memory must have been created with a memory type that reports
> VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT

Since there's no guarantee that there's any memory that is *both*
device-local *and* host-visible, let's just use the latter requirement.
