IVGCVSW-6634 SubgraphView: Add method of returning a GetSubgraphWorkingCopy

 * Add pointer to SubgraphView allowing it to store a working copy
   implementation of its own representation of graph.
 * Make SubgraphView a friend of Graph to allow access to layers.
 * Add constructor to SubgraphView taking SubgraphViewWorkingCopyPtr
 * Rewrite Graph::SubstituteSubgraph for use on SubgraphView
 * Add GetWorkingCopy() method
 * Add tests for replacement of multiplication with DepthwiseConv2d
 * Check GetBackendHint() has value before passing to PrecompiledLayer
 * Add GetOwningIConnectableLayer to IInputSlot to allow traversing from
   IConnectableLayer->IOutputSlot->IInputSlot->IConnectableLayer
