Add a minimal implementation of VK_KHR_device_group_creation.

This is the instance half of device-group support. This provides the
means to enumerate all known physical device groups, and to create
grouped logical devices.

This provides just enough to satisfy the Vulkan spec. Metal won't
support this fully until Metal 3.0 in the upcoming macOS 10.15.
