[ Compiler ] Implement bn realizer with test
This patch completes the bn realizer for the inference.
This path is only for the inference and therefore it supposed to 1 to
1 connection ( one input and one output for the bn layer ) in the
model graph. That means if there are multiple connections, then
multi-out layer is follows and make sure bn layer has 1 to 1
in/output during compilation.
