Summary: This is the recommended way to write quantizers according
to https://pytorch.org/tutorials/prototype/pt2e_quantizer.html#a-note-on-ir-for-pt2e-quantization-flow.
It is agnostic to changes in the aten IR and can be easily extended
to support conv1d-bn and conv3d-bn fusion patterns in the future.
This is the first step towards rewriting XNNPACKQuantizer using
this subgraph matcher.
