Fix a bug in the LowerLayers pass where operations with inner symbols inside layerblocks would not have their HierPathOp users updated when these operations were moved into new modules. Fix this by recording a mapping of modifications to InnerRefAttrs and then applying these to HierPathOps after all modules are processed. Fixes #6717.
