[graphite] Don't delete MTLDepthStencilState until CommandBuffer is done

Browse Source 
The MTLDepthStencilState objects are only refed in  MtlResourceProvider.
When we shut down, we tear down all the Recorders. That tears down their
resource providers, which in the Metal case deletes these DepthStencil
objects. But we can have a command buffer still in flight, so we need to
add a ref to keep those objects alive.
