vulkan: Track which objects are client-visible

When dealing with debug logging, it's useful to track when an object's
construction is finished and it's now visible to the client.  We can
detect this pretty easily by setting a flag the first time foo_to_handle
is called.  As long as drivers only ever call that function at the end
of object construction (they all do to my knowledge), this should be a
reliable mechanism for detecting when a client knows about a handle.
