layers: VkDestroyInstance+VkDestroyDevice clear ObjectTracker maps

Don't complain about lingering objects more than once.
Once their device or instance is gone don't keep their information around.
This should change dramatically to have independent maps for each instance/device.
Don't complain about other devices remaining in vkDestroyDevice.
