Subject: [Vulkan] Check each device capabilities before selecting it.

Split instance and physical device selection function and move device selection to window creation, to reject devices without present capability.
Add device preferred type check in discrete > integrated > virtual > cpu > other order.
Add device list printout.
Add command line argument to override device selection.
