Add a couple of new samples, improved some others: (#414)

new:
- InstanceVersion: print out the instance version
- PhysicalDeviceExtensions: print out the device specific extensions
- PhysicalDeviceFeatures: print out the device specific features
- PhysicalDeviceGroups: print out the device groups (interesting with SLI)
- PhysicalDeviceMemoryProperties: print out the device specific memory properties
- PhysicalDeviceQueueFamilyProperties: print out the device specific queue family properties
- SurfaceCapabilities: print out the surface specific capabilities
- SurfaceFormats: print out the supported surface specific formats
improved:
- InstanceExtensionProperties: print out the instance extensions alphabetically
- InstanceLayerProperties: removed an unused local function
- RayTracing: improved fence usage
