vulkan: Cleanup PhysicalDevice and Instance querying (#4632)1.1.698

* vulkan: Move most of the properties enumeration to VulkanPhysicalDevice That clean up a bit of duplicate logic. Also move to use an hashset for device extensions. * vulkan: Move instance querying to VulkanInstance Also cleanup code to use span when possible instead of unsafe pointers. * Address gdkchan's comments
